### Breaking Changes
> These changes affect only code written against previous beta versions of `v1.7.0` and `v1.8.0`
* The function `NewTokenCredential` has been removed from the `fake` package. Use a literal `&fake.TokenCredential{}` instead.

# Azure Core Client Module for Go
[![PkgGoDev](https://pkg.go.dev/badge/github.com/Azure/azure-sdk-for-go/sdk/azcore)](https://pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/azcore)
[![Build Status](https://dev.azure.com/azure-sdk/public/_apis/build/status/go/go%20-%20azcore%20-%20ci?branchName=main)](https://dev.azure.com/azure-sdk/public/_build/latest?definitionId=1843&branchName=main)
[![Code Coverage](https://img.shields.io/azure-devops/coverage/azure-sdk/public/1843/main)](https://img.shields.io/azure-devops/coverage/azure-sdk/public/1843/main)
The `azcore` module provides a set of common interfaces and types for Go SDK client modules.
These modules follow the [Azure SDK Design Guidelines for Go](https://azure.github.io/azure-sdk/golang_introduction.html).
## Getting started
This project uses [Go modules](https://github.com/golang/go/wiki/Modules) for versioning and dependency management.
Typically, you will not need to explicitly install `azcore` as it will be installed as a client module dependency.
To add the latest version to your `go.mod` file, execute the following command.
```bash
go get github.com/Azure/azure-sdk-for-go/sdk/azcore
```
General documentation and examples can be found on [pkg.go.dev](https://pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/azcore).

Package cloud implements a configuration API for applications deployed to sovereign or private Azure clouds.
Azure SDK client configuration defaults are appropriate for Azure Public Cloud (sometimes referred to as
"Azure Commercial" or simply "Microsoft Azure"). This package enables applications deployed to other
Azure Clouds to configure clients appropriately.
This package contains predefined configuration for well-known sovereign clouds such as Azure Government and
Azure China. Azure SDK clients accept this configuration via the Cloud field of azcore.ClientOptions. For
example, configuring a credential and ARM client for Azure Government:
opts := azcore.ClientOptions{Cloud: cloud.AzureGovernment}
cred, err := azidentity.NewDefaultAzureCredential(
&azidentity.DefaultAzureCredentialOptions{ClientOptions: opts},
)
handle(err)
client, err := armsubscription.NewClient(
cred, &arm.ClientOptions{ClientOptions: opts},
)
handle(err)
Applications deployed to a private cloud such as Azure Stack create a Configuration object with
appropriate values:
c := cloud.Configuration{
ActiveDirectoryAuthorityHost: "https://...",
Services: map[cloud.ServiceName]cloud.ServiceConfiguration{
cloud.ResourceManager: {
Audience: "...",
Endpoint: "https://...",
},
},
}
opts := azcore.ClientOptions{Cloud: c}
cred, err := azidentity.NewDefaultAzureCredential(
&azidentity.DefaultAzureCredentialOptions{ClientOptions: opts},
)
handle(err)
client, err := armsubscription.NewClient(
cred, &arm.ClientOptions{ClientOptions: opts},

Package azcore implements an HTTP request/response middleware pipeline used by Azure SDK clients.
The middleware consists of three components.
- One or more Policy instances.
- A Transporter instance.
- A Pipeline instance that combines the Policy and Transporter instances.
# Implementing the Policy Interface
A Policy can be implemented in two ways; as a first-class function for a stateless Policy, or as
a method on a type for a stateful Policy. Note that HTTP requests made via the same pipeline share
the same Policy instances, so if a Policy mutates its state it MUST be properly synchronized to
avoid race conditions.
A Policy's Do method is called when an HTTP request wants to be sent over the network. The Do method can
perform any operation(s) it desires. For example, it can log the outgoing request, mutate the URL, headers,
and/or query parameters, inject a failure, etc. Once the Policy has successfully completed its request
work, it must call the Next() method on the *policy.Request instance in order to pass the request to the
next Policy in the chain.
When an HTTP response comes back, the Policy then gets a chance to process the response/error. The Policy instance
can log the response, retry the operation if it failed due to a transient error or timeout, unmarshal the response
body, etc. Once the Policy has successfully completed its response work, it must return the *http.Response
and error instances to its caller.
Template for implementing a stateless Policy:
type policyFunc func(*policy.Request) (*http.Response, error)
// Do implements the Policy interface on policyFunc.
func (pf policyFunc) Do(req *policy.Request) (*http.Response, error) {
return pf(req)
}
func NewMyStatelessPolicy() policy.Policy {
return policyFunc(func(req *policy.Request) (*http.Response, error) {
// TODO: mutate/process Request here
// forward Request to next Policy & get Response/error
resp, err := req.Next()
// TODO: mutate/process Response/error here
// return Response/error to previous Policy
return resp, err
})
}
Template for implementing a stateful Policy:
type MyStatefulPolicy struct {
// TODO: add configuration/setting fields here
}
// TODO: add initialization args to NewMyStatefulPolicy()
func NewMyStatefulPolicy() policy.Policy {
return &MyStatefulPolicy{
// TODO: initialize configuration/setting fields here
}
}
func (p *MyStatefulPolicy) Do(req *policy.Request) (resp *http.Response, err error) {
// TODO: mutate/process Request here
// forward Request to next Policy & get Response/error
resp, err := req.Next()
// TODO: mutate/process Response/error here
// return Response/error to previous Policy
return resp, err
}
# Implementing the Transporter Interface
The Transporter interface is responsible for sending the HTTP request and returning the corresponding
HTTP response or error. The Transporter is invoked by the last Policy in the chain. The default Transporter
implementation uses a shared http.Client from the standard library.
The same stateful/stateless rules for Policy implementations apply to Transporter implementations.
# Using Policy and Transporter Instances Via a Pipeline
To use the Policy and Transporter instances, an application passes them to the runtime.NewPipeline function.
func NewPipeline(transport Transporter, policies ...Policy) Pipeline
The specified Policy instances form a chain and are invoked in the order provided to NewPipeline
followed by the Transporter.
Once the Pipeline has been created, create a runtime.Request instance and pass it to Pipeline's Do method.
func NewRequest(ctx context.Context, httpMethod string, endpoint string) (*Request, error)
func (p Pipeline) Do(req *Request) (*http.Request, error)
The Pipeline.Do method sends the specified Request through the chain of Policy and Transporter
instances. The response/error is then sent through the same chain of Policy instances in reverse
order. For example, assuming there are Policy types PolicyA, PolicyB, and PolicyC along with
TransportA.
pipeline := NewPipeline(TransportA, PolicyA, PolicyB, PolicyC)
The flow of Request and Response looks like the following:
policy.Request -> PolicyA -> PolicyB -> PolicyC -> TransportA -----+
|
HTTP(S) endpoint
|
caller <--------- PolicyA <- PolicyB <- PolicyC <- http.Response-+
# Creating a Request Instance
The Request instance passed to Pipeline's Do method is a wrapper around an *http.Request. It also
contains some internal state and provides various convenience methods. You create a Request instance
by calling the runtime.NewRequest function:
func NewRequest(ctx context.Context, httpMethod string, endpoint string) (*Request, error)
If the Request should contain a body, call the SetBody method.
func (req *Request) SetBody(body ReadSeekCloser, contentType string) error
A seekable stream is required so that upon retry, the retry Policy instance can seek the stream
back to the beginning before retrying the network request and re-uploading the body.
# Sending an Explicit Null
Operations like JSON-MERGE-PATCH send a JSON null to indicate a value should be deleted.
{
"delete-me": null
}
This requirement conflicts with the SDK's default marshalling that specifies "omitempty" as
a means to resolve the ambiguity between a field to be excluded and its zero-value.
type Widget struct {
Name *string `json:",omitempty"`
Count *int `json:",omitempty"`
}
In the above example, Name and Count are defined as pointer-to-type to disambiguate between
a missing value (nil) and a zero-value (0) which might have semantic differences.
In a PATCH operation, any fields left as nil are to have their values preserved. When updating
a Widget's count, one simply specifies the new value for Count, leaving Name nil.
To fulfill the requirement for sending a JSON null, the NullValue() function can be used.
w := Widget{
Count: azcore.NullValue[*int](),
}
This sends an explict "null" for Count, indicating that any current value for Count should be deleted.
# Processing the Response
When the HTTP response is received, the *http.Response is returned directly. Each Policy instance
can inspect/mutate the *http.Response.
# Built-in Logging
To enable logging, set environment variable AZURE_SDK_GO_LOGGING to "all" before executing your program.
By default the logger writes to stderr. This can be customized by calling log.SetListener, providing
a callback that writes to the desired location. Any custom logging implementation MUST provide its
own synchronization to handle concurrent invocations.
See the docs for the log package for further details.
# Pageable Operations
Pageable operations return potentially large data sets spread over multiple GET requests. The result of
each GET is a "page" of data consisting of a slice of items.
Pageable operations can be identified by their New*Pager naming convention and return type of *runtime.Pager[T].
func (c *WidgetClient) NewListWidgetsPager(o *Options) *runtime.Pager[PageResponse]
The call to WidgetClient.NewListWidgetsPager() returns an instance of *runtime.Pager[T] for fetching pages
and determining if there are more pages to fetch. No IO calls are made until the NextPage() method is invoked.
pager := widgetClient.NewListWidgetsPager(nil)
for pager.More() {
page, err := pager.NextPage(context.TODO())
// handle err
for _, widget := range page.Values {
// process widget
}
}
# Long-Running Operations
Long-running operations (LROs) are operations consisting of an initial request to start the operation followed
by polling to determine when the operation has reached a terminal state. An LRO's terminal state is one
of the following values.
- Succeeded - the LRO completed successfully
- Failed - the LRO failed to complete
- Canceled - the LRO was canceled
LROs can be identified by their Begin* prefix and their return type of *runtime.Poller[T].
func (c *WidgetClient) BeginCreateOrUpdate(ctx context.Context, w Widget, o *Options) (*runtime.Poller[Response], error)
When a call to WidgetClient.BeginCreateOrUpdate() returns a nil error, it means that the LRO has started.
It does _not_ mean that the widget has been created or updated (or failed to be created/updated).
The *runtime.Poller[T] provides APIs for determining the state of the LRO. To wait for the LRO to complete,
call the PollUntilDone() method.
poller, err := widgetClient.BeginCreateOrUpdate(context.TODO(), Widget{}, nil)
// handle err
result, err := poller.PollUntilDone(context.TODO(), nil)
// handle err
// use result
The call to PollUntilDone() will block the current goroutine until the LRO has reached a terminal state or the
context is canceled/timed out.
Note that LROs can take anywhere from several seconds to several minutes. The duration is operation-dependent. Due to
this variant behavior, pollers do _not_ have a preconfigured time-out. Use a context with the appropriate cancellation
mechanism as required.
# Resume Tokens
Pollers provide the ability to serialize their state into a "resume token" which can be used by another process to
recreate the poller. This is achieved via the runtime.Poller[T].ResumeToken() method.
token, err := poller.ResumeToken()
// handle error
Note that a token can only be obtained for a poller that's in a non-terminal state. Also note that any subsequent calls
to poller.Poll() might change the poller's state. In this case, a new token should be created.
After the token has been obtained, it can be used to recreate an instance of the originating poller.
poller, err := widgetClient.BeginCreateOrUpdate(nil, Widget{}, &Options{
ResumeToken: token,
})
When resuming a poller, no IO is performed, and zero-value arguments can be used for everything but the Options.ResumeToken.
Resume tokens are unique per service client and operation. Attempting to resume a poller for LRO BeginB() with a token from LRO
BeginA() will result in an error.
# Fakes
The fake package contains types used for constructing in-memory fake servers used in unit tests.
This allows writing tests to cover various success/error conditions without the need for connecting to a live service.
Please see https://github.com/Azure/azure-sdk-for-go/tree/main/sdk/samples/fakes for details and examples on how to use fakes.

> These changes affect only code written against a beta version such as v1.4.0-beta.4
* Whether `GetToken` requests a CAE token is now determined by `TokenRequestOptions.EnableCAE`. Azure
SDK clients which support CAE will set this option automatically. Credentials no longer request CAE
tokens by default or observe the environment variable "AZURE_IDENTITY_DISABLE_CP1".
### Bugs Fixed
* Credential chains such as `DefaultAzureCredential` now try their next credential, if any, when
managed identity authentication fails in a Docker Desktop container
([#21417](https://github.com/Azure/azure-sdk-for-go/issues/21417))

## 1.3.0-beta.5 (2023-04-11)
### Breaking Changes
> These changes affect only code written against a beta version such as v1.3.0-beta.4
* Moved `NewWorkloadIdentityCredential()` parameters into `WorkloadIdentityCredentialOptions`.
The constructor now reads default configuration from environment variables set by the Azure
workload identity webhook by default.
([#20478](https://github.com/Azure/azure-sdk-for-go/pull/20478))
* Removed CAE support. It will return in v1.4.0-beta.1
([#20479](https://github.com/Azure/azure-sdk-for-go/pull/20479))

### Bugs Fixed
* Credentials now synchronize within `GetToken()` so a single instance can be shared among goroutines
([#20044](https://github.com/Azure/azure-sdk-for-go/issues/20044))
### Other Changes
* Upgraded dependencies
## 1.2.2 (2023-03-07)
### Other Changes
* Upgraded dependencies
## 1.3.0-beta.3 (2023-02-07)
### Features Added
* By default, credentials set client capability "CP1" to enable support for
[Continuous Access Evaluation (CAE)](https://docs.microsoft.com/azure/active-directory/develop/app-resilience-continuous-access-evaluation).
This indicates to Microsoft Entra ID that your application can handle CAE claims challenges.
You can disable this behavior by setting the environment variable "AZURE_IDENTITY_DISABLE_CP1" to "true".
* `InteractiveBrowserCredentialOptions.LoginHint` enables pre-populating the login
prompt with a username ([#15599](https://github.com/Azure/azure-sdk-for-go/pull/15599))
* Service principal and user credentials support ADFS authentication on Azure Stack.
Specify "adfs" as the credential's tenant.
* Applications running in private or disconnected clouds can prevent credentials from
requesting Microsoft Entra instance metadata by setting the `DisableInstanceDiscovery`
field on credential options.
* Many credentials can now be configured to authenticate in multiple tenants. The
options types for these credentials have an `AdditionallyAllowedTenants` field
that specifies additional tenants in which the credential may authenticate.
## 1.3.0-beta.2 (2023-01-10)
### Features Added
* Added `OnBehalfOfCredential` to support the on-behalf-of flow
([#16642](https://github.com/Azure/azure-sdk-for-go/issues/16642))
### Bugs Fixed
* `AzureCLICredential` reports token expiration in local time (should be UTC)
### Other Changes
* `AzureCLICredential` imposes its default timeout only when the `Context`
passed to `GetToken()` has no deadline
* Added `NewCredentialUnavailableError()`. This function constructs an error indicating
a credential can't authenticate and an encompassing `ChainedTokenCredential` should
try its next credential, if any.
## 1.3.0-beta.1 (2022-12-13)
### Features Added
* `WorkloadIdentityCredential` and `DefaultAzureCredential` support
Workload Identity Federation on Kubernetes. `DefaultAzureCredential`
support requires environment variable configuration as set by the
Workload Identity webhook.
([#15615](https://github.com/Azure/azure-sdk-for-go/issues/15615))
## 1.2.0 (2022-11-08)
### Other Changes
* This version includes all fixes and features from 1.2.0-beta.*
## 1.2.0-beta.3 (2022-10-11)

## 1.2.0-beta.1 (2022-06-07)
### Features Added
* `EnvironmentCredential` reads certificate passwords from `AZURE_CLIENT_CERTIFICATE_PASSWORD`
([#17099](https://github.com/Azure/azure-sdk-for-go/pull/17099))
## 1.1.0 (2022-06-07)
### Features Added
* `ClientCertificateCredential` and `ClientSecretCredential` support ESTS-R. First-party
applications can set environment variable `AZURE_REGIONAL_AUTHORITY_NAME` with a
region name.
([#15605](https://github.com/Azure/azure-sdk-for-go/issues/15605))
## 1.0.1 (2022-06-07)
### Other Changes
* Upgrade `microsoft-authentication-library-for-go` requirement to v0.5.1
([#18176](https://github.com/Azure/azure-sdk-for-go/issues/18176))
## 1.0.0 (2022-05-12)
### Features Added
* `DefaultAzureCredential` reads environment variable `AZURE_CLIENT_ID` for the
client ID of a user-assigned managed identity
([#17293](https://github.com/Azure/azure-sdk-for-go/pull/17293))
### Breaking Changes
* Removed `AuthorizationCodeCredential`. Use `InteractiveBrowserCredential` instead
to authenticate a user with the authorization code flow.
* Instances of `AuthenticationFailedError` are now returned by pointer.
* `GetToken()` returns `azcore.AccessToken` by value
### Bugs Fixed
* `AzureCLICredential` panics after receiving an unexpected error type
([#17490](https://github.com/Azure/azure-sdk-for-go/issues/17490))
### Other Changes
* `GetToken()` returns an error when the caller specifies no scope
* Updated to the latest versions of `golang.org/x/crypto`, `azcore` and `internal`
## 0.14.0 (2022-04-05)
### Breaking Changes
* This module now requires Go 1.18
* Removed `AuthorityHost`. Credentials are now configured for sovereign or private
clouds with the API in `azcore/cloud`, for example:
```go
// before
opts := azidentity.ClientSecretCredentialOptions{AuthorityHost: azidentity.AzureGovernment}
cred, err := azidentity.NewClientSecretCredential(tenantID, clientID, secret, &opts)
// after
import "github.com/Azure/azure-sdk-for-go/sdk/azcore/cloud"
opts := azidentity.ClientSecretCredentialOptions{}
opts.Cloud = cloud.AzureGovernment
cred, err := azidentity.NewClientSecretCredential(tenantID, clientID, secret, &opts)
```
## 0.13.2 (2022-03-08)
### Bugs Fixed
* Prevented a data race in `DefaultAzureCredential` and `ChainedTokenCredential`
([#17144](https://github.com/Azure/azure-sdk-for-go/issues/17144))
### Other Changes
* Upgraded App Service managed identity version from 2017-09-01 to 2019-08-01
([#17086](https://github.com/Azure/azure-sdk-for-go/pull/17086))
## 0.13.1 (2022-02-08)
### Features Added
* `EnvironmentCredential` supports certificate SNI authentication when
`AZURE_CLIENT_SEND_CERTIFICATE_CHAIN` is "true".
([#16851](https://github.com/Azure/azure-sdk-for-go/pull/16851))
### Bugs Fixed
* `ManagedIdentityCredential.GetToken()` now returns an error when configured for
a user assigned identity in Azure Cloud Shell (which doesn't support such identities)
([#16946](https://github.com/Azure/azure-sdk-for-go/pull/16946))
### Other Changes
* `NewDefaultAzureCredential()` logs non-fatal errors. These errors are also included in the
error returned by `DefaultAzureCredential.GetToken()` when it's unable to acquire a token
from any source. ([#15923](https://github.com/Azure/azure-sdk-for-go/issues/15923))
## 0.13.0 (2022-01-11)
### Breaking Changes
* Replaced `AuthenticationFailedError.RawResponse()` with a field having the same name
* Unexported `CredentialUnavailableError`
* Instances of `ChainedTokenCredential` will now skip looping through the list of source credentials and re-use the first successful credential on subsequent calls to `GetToken`.
* If `ChainedTokenCredentialOptions.RetrySources` is true, `ChainedTokenCredential` will continue to try all of the originally provided credentials each time the `GetToken` method is called.
* `ChainedTokenCredential.successfulCredential` will contain a reference to the last successful credential.
* `DefaultAzureCredenial` will also re-use the first successful credential on subsequent calls to `GetToken`.
* `DefaultAzureCredential.chain.successfulCredential` will also contain a reference to the last successful credential.
### Other Changes
* `ManagedIdentityCredential` no longer probes IMDS before requesting a token
from it. Also, an error response from IMDS no longer disables a credential
instance. Following an error, a credential instance will continue to send
requests to IMDS as necessary.
* Adopted MSAL for user and service principal authentication
* Updated `azcore` requirement to 0.21.0
## 0.12.0 (2021-11-02)
### Breaking Changes
* Raised minimum go version to 1.16
* Removed `NewAuthenticationPolicy()` from credentials. Clients should instead use azcore's
`runtime.NewBearerTokenPolicy()` to construct a bearer token authorization policy.
* The `AuthorityHost` field in credential options structs is now a custom type,
`AuthorityHost`, with underlying type `string`
* `NewChainedTokenCredential` has a new signature to accommodate a placeholder
options struct:
```go
// before
cred, err := NewChainedTokenCredential(credA, credB)
// after
cred, err := NewChainedTokenCredential([]azcore.TokenCredential{credA, credB}, nil)
```
* Removed `ExcludeAzureCLICredential`, `ExcludeEnvironmentCredential`, and `ExcludeMSICredential`
from `DefaultAzureCredentialOptions`
* `NewClientCertificateCredential` requires a `[]*x509.Certificate` and `crypto.PrivateKey` instead of
a path to a certificate file. Added `ParseCertificates` to simplify getting these in common cases:
```go
// before
cred, err := NewClientCertificateCredential("tenant", "client-id", "/cert.pem", nil)
// after
certData, err := os.ReadFile("/cert.pem")
certs, key, err := ParseCertificates(certData, password)
cred, err := NewClientCertificateCredential(tenantID, clientID, certs, key, nil)
```
* Removed `InteractiveBrowserCredentialOptions.ClientSecret` and `.Port`
* Removed `AADAuthenticationFailedError`
* Removed `id` parameter of `NewManagedIdentityCredential()`. User assigned identities are now
specified by `ManagedIdentityCredentialOptions.ID`:
```go
// before
cred, err := NewManagedIdentityCredential("client-id", nil)
// or, for a resource ID
opts := &ManagedIdentityCredentialOptions{ID: ResourceID}
cred, err := NewManagedIdentityCredential("/subscriptions/...", opts)
// after
clientID := ClientID("7cf7db0d-...")
opts := &ManagedIdentityCredentialOptions{ID: clientID}
// or, for a resource ID
resID: ResourceID("/subscriptions/...")
opts := &ManagedIdentityCredentialOptions{ID: resID}
cred, err := NewManagedIdentityCredential(opts)
```
* `DeviceCodeCredentialOptions.UserPrompt` has a new type: `func(context.Context, DeviceCodeMessage) error`
* Credential options structs now embed `azcore.ClientOptions`. In addition to changing literal initialization
syntax, this change renames `HTTPClient` fields to `Transport`.
* Renamed `LogCredential` to `EventCredential`
* `AzureCLICredential` no longer reads the environment variable `AZURE_CLI_PATH`
* `NewManagedIdentityCredential` no longer reads environment variables `AZURE_CLIENT_ID` and
`AZURE_RESOURCE_ID`. Use `ManagedIdentityCredentialOptions.ID` instead.
* Unexported `AuthenticationFailedError` and `CredentialUnavailableError` structs. In their place are two
interfaces having the same names.
### Bugs Fixed
* `AzureCLICredential.GetToken` no longer mutates its `opts.Scopes`
### Features Added
* Added connection configuration options to `DefaultAzureCredentialOptions`
* `AuthenticationFailedError.RawResponse()` returns the HTTP response motivating the error,
if available
### Other Changes
* `NewDefaultAzureCredential()` returns `*DefaultAzureCredential` instead of `*ChainedTokenCredential`
* Added `TenantID` field to `DefaultAzureCredentialOptions` and `AzureCLICredentialOptions`
## 0.11.0 (2021-09-08)
### Breaking Changes
* Unexported `AzureCLICredentialOptions.TokenProvider` and its type,
`AzureCLITokenProvider`
### Bug Fixes
* `ManagedIdentityCredential.GetToken` returns `CredentialUnavailableError`
when IMDS has no assigned identity, signaling `DefaultAzureCredential` to
try other credentials
## 0.10.0 (2021-08-30)
### Breaking Changes
* Update based on `azcore` refactor [#15383](https://github.com/Azure/azure-sdk-for-go/pull/15383)
## 0.9.3 (2021-08-20)

# Migrating from autorest/adal to azidentity
`azidentity` provides Microsoft Entra ID ([formerly Azure Active Directory](https://learn.microsoft.com/azure/active-directory/fundamentals/new-name)) authentication for the newest Azure SDK modules (`github.com/azure-sdk-for-go/sdk/...`). Older Azure SDK packages (`github.com/azure-sdk-for-go/services/...`) use types from `github.com/go-autorest/autorest/adal` instead.
This guide shows common authentication code using `autorest/adal` and its equivalent using `azidentity`.
## Table of contents
- [Acquire a token](#acquire-a-token)
- [Client certificate authentication](#client-certificate-authentication)
- [Client secret authentication](#client-secret-authentication)
- [Configuration](#configuration)
- [Device code authentication](#device-code-authentication)
- [Managed identity](#managed-identity)
- [Use azidentity credentials with older packages](#use-azidentity-credentials-with-older-packages)
## Configuration
### `autorest/adal`
Token providers require a token audience (resource identifier) and an instance of `adal.OAuthConfig`, which requires a Microsoft Entra endpoint and tenant:
```go
import "github.com/Azure/go-autorest/autorest/adal"
oauthCfg, err := adal.NewOAuthConfig("https://login.chinacloudapi.cn", tenantID)
handle(err)
spt, err := adal.NewServicePrincipalTokenWithSecret(
*oauthCfg, clientID, "https://management.chinacloudapi.cn/", &adal.ServicePrincipalTokenSecret{ClientSecret: secret},
)
```
### `azidentity`
A credential instance can acquire tokens for any audience. The audience for each token is determined by the client requesting it. Credentials require endpoint configuration only for sovereign or private clouds. The `azcore/cloud` package has predefined configuration for sovereign clouds such as Azure China:
```go
import (
"github.com/Azure/azure-sdk-for-go/sdk/azcore/cloud"
"github.com/Azure/azure-sdk-for-go/sdk/azidentity"
)
clientOpts := azcore.ClientOptions{Cloud: cloud.AzureChina}
cred, err := azidentity.NewClientSecretCredential(
tenantID, clientID, secret, &azidentity.ClientSecretCredentialOptions{ClientOptions: clientOpts},
)
handle(err)
```
## Client secret authentication
### `autorest/adal`
```go
import (
"github.com/Azure/azure-sdk-for-go/services/resources/mgmt/2018-06-01/subscriptions"
"github.com/Azure/go-autorest/autorest"
"github.com/Azure/go-autorest/autorest/adal"
)
oauthCfg, err := adal.NewOAuthConfig("https://login.microsoftonline.com", tenantID)
handle(err)
spt, err := adal.NewServicePrincipalTokenWithSecret(
*oauthCfg, clientID, "https://management.azure.com/", &adal.ServicePrincipalTokenSecret{ClientSecret: secret},
)
handle(err)
client := subscriptions.NewClient()
client.Authorizer = autorest.NewBearerAuthorizer(spt)
```
### `azidentity`
```go
import (
"github.com/Azure/azure-sdk-for-go/sdk/azidentity"
"github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/resources/armsubscriptions"
)
cred, err := azidentity.NewClientSecretCredential(tenantID, clientID, secret, nil)
handle(err)
client, err := armsubscriptions.NewClient(cred, nil)
handle(err)
```
## Client certificate authentication
### `autorest/adal`
```go
import (
"os"
"github.com/Azure/azure-sdk-for-go/services/resources/mgmt/2018-06-01/subscriptions"
"github.com/Azure/go-autorest/autorest"
"github.com/Azure/go-autorest/autorest/adal"
)
certData, err := os.ReadFile("./example.pfx")
handle(err)
certificate, rsaPrivateKey, err := decodePkcs12(certData, "")
handle(err)
oauthCfg, err := adal.NewOAuthConfig("https://login.microsoftonline.com", tenantID)
handle(err)
spt, err := adal.NewServicePrincipalTokenFromCertificate(
*oauthConfig, clientID, certificate, rsaPrivateKey, "https://management.azure.com/",
)
client := subscriptions.NewClient()
client.Authorizer = autorest.NewBearerAuthorizer(spt)
```
### `azidentity`
```go
import (
"os"
"github.com/Azure/azure-sdk-for-go/sdk/azidentity"
"github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/resources/armsubscriptions"
)
certData, err := os.ReadFile("./example.pfx")
handle(err)
certs, key, err := azidentity.ParseCertificates(certData, nil)
handle(err)
cred, err = azidentity.NewClientCertificateCredential(tenantID, clientID, certs, key, nil)
handle(err)
client, err := armsubscriptions.NewClient(cred, nil)
handle(err)
```
## Managed identity
### `autorest/adal`
```go
import (
"github.com/Azure/azure-sdk-for-go/services/resources/mgmt/2018-06-01/subscriptions"
"github.com/Azure/go-autorest/autorest"
"github.com/Azure/go-autorest/autorest/adal"
)
spt, err := adal.NewServicePrincipalTokenFromManagedIdentity("https://management.azure.com/", nil)
handle(err)
client := subscriptions.NewClient()
client.Authorizer = autorest.NewBearerAuthorizer(spt)
```
### `azidentity`
```go
import (
"github.com/Azure/azure-sdk-for-go/sdk/azidentity"
"github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/resources/armsubscriptions"
)
cred, err := azidentity.NewManagedIdentityCredential(nil)
handle(err)
client, err := armsubscriptions.NewClient(cred, nil)
handle(err)
```
### User-assigned identities
`autorest/adal`:
```go
import "github.com/Azure/go-autorest/autorest/adal"
opts := &adal.ManagedIdentityOptions{ClientID: "..."}
spt, err := adal.NewServicePrincipalTokenFromManagedIdentity("https://management.azure.com/")
handle(err)
```
`azidentity`:
```go
import "github.com/Azure/azure-sdk-for-go/sdk/azidentity"
opts := azidentity.ManagedIdentityCredentialOptions{ID: azidentity.ClientID("...")}
cred, err := azidentity.NewManagedIdentityCredential(&opts)
handle(err)
```
## Device code authentication
### `autorest/adal`
```go
import (
"fmt"
"net/http"
"github.com/Azure/azure-sdk-for-go/services/resources/mgmt/2018-06-01/subscriptions"
"github.com/Azure/go-autorest/autorest"
"github.com/Azure/go-autorest/autorest/adal"
)
oauthClient := &http.Client{}
oauthCfg, err := adal.NewOAuthConfig("https://login.microsoftonline.com", tenantID)
handle(err)
resource := "https://management.azure.com/"
deviceCode, err := adal.InitiateDeviceAuth(oauthClient, *oauthCfg, clientID, resource)
handle(err)
// display instructions, wait for the user to authenticate
fmt.Println(*deviceCode.Message)
token, err := adal.WaitForUserCompletion(oauthClient, deviceCode)
handle(err)
spt, err := adal.NewServicePrincipalTokenFromManualToken(*oauthCfg, clientID, resource, *token)
handle(err)
client := subscriptions.NewClient()
client.Authorizer = autorest.NewBearerAuthorizer(spt)
```
### `azidentity`
```go
import (
"github.com/Azure/azure-sdk-for-go/sdk/azidentity"
"github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/resources/armsubscriptions"
)
cred, err := azidentity.NewDeviceCodeCredential(nil)
handle(err)
client, err := armsubscriptions.NewSubscriptionsClient(cred, nil)
handle(err)
```
`azidentity.DeviceCodeCredential` will guide a user through authentication, printing instructions to the console by default. The user prompt is customizable. For more information, see the [package documentation](https://pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/azidentity#DeviceCodeCredential).
## Acquire a token
### `autorest/adal`
```go
import "github.com/Azure/go-autorest/autorest/adal"
oauthCfg, err := adal.NewOAuthConfig("https://login.microsoftonline.com", tenantID)
handle(err)
spt, err := adal.NewServicePrincipalTokenWithSecret(
*oauthCfg, clientID, "https://vault.azure.net", &adal.ServicePrincipalTokenSecret{ClientSecret: secret},
)
err = spt.Refresh()
if err == nil {
token := spt.Token
}
```
### `azidentity`
In ordinary usage, application code doesn't need to request tokens from credentials directly. Azure SDK clients handle token acquisition and refreshing internally. However, applications may call `GetToken()` to do so. All credential types have this method.
```go
import (
"github.com/Azure/azure-sdk-for-go/sdk/azcore/policy"
"github.com/Azure/azure-sdk-for-go/sdk/azidentity"
)
cred, err := azidentity.NewClientSecretCredential(tenantID, clientID, secret, nil)
handle(err)
tk, err := cred.GetToken(
context.TODO(), policy.TokenRequestOptions{Scopes: []string{"https://vault.azure.net/.default"}},
)
if err == nil {
token := tk.Token
}
```
Note that `azidentity` credentials use the Microsoft Entra endpoint, which requires OAuth 2 scopes instead of the resource identifiers `autorest/adal` expects. For more information, see [Microsoft Entra ID documentation](https://learn.microsoft.com/azure/active-directory/develop/permissions-consent-overview).
## Use azidentity credentials with older packages
The [azidext module](https://pkg.go.dev/github.com/jongio/azidext/go/azidext) provides an adapter for `azidentity` credential types. The adapter enables using the credential types with older Azure SDK clients. For example:
```go
import (
"github.com/Azure/azure-sdk-for-go/sdk/azidentity"
"github.com/Azure/azure-sdk-for-go/services/resources/mgmt/2018-06-01/subscriptions"
"github.com/jongio/azidext/go/azidext"
)
cred, err := azidentity.NewClientSecretCredential(tenantID, clientID, secret, nil)
handle(err)
client := subscriptions.NewClient()
client.Authorizer = azidext.NewTokenCredentialAdapter(cred, []string{"https://management.azure.com//.default"})
```

# Azure Identity Client Module for Go
The Azure Identity module provides Microsoft Entra ID ([formerly Azure Active Directory](https://learn.microsoft.com/azure/active-directory/fundamentals/new-name)) token authentication support across the Azure SDK. It includes a set of `TokenCredential` implementations, which can be used with Azure SDK clients supporting token authentication.
[![PkgGoDev](https://pkg.go.dev/badge/github.com/Azure/azure-sdk-for-go/sdk/azidentity)](https://pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/azidentity)
| [Microsoft Entra ID documentation](https://learn.microsoft.com/azure/active-directory/)
| [Source code](https://github.com/Azure/azure-sdk-for-go/tree/main/sdk/azidentity)
# Getting started
## Install the module
This project uses [Go modules](https://github.com/golang/go/wiki/Modules) for versioning and dependency management.
Install the Azure Identity module:
```sh
go get -u github.com/Azure/azure-sdk-for-go/sdk/azidentity
```
## Prerequisites
- an [Azure subscription](https://azure.microsoft.com/free/)
- Go 1.18
### Authenticating during local development
When debugging and executing code locally, developers typically use their own accounts to authenticate calls to Azure services. The `azidentity` module supports authenticating through developer tools to simplify local development.
#### Authenticating via the Azure CLI
`DefaultAzureCredential` and `AzureCLICredential` can authenticate as the user
signed in to the [Azure CLI](https://docs.microsoft.com/cli/azure). To sign in to the Azure CLI, run `az login`. On a system with a default web browser, the Azure CLI will launch the browser to authenticate a user.
When no default browser is available, `az login` will use the device code
authentication flow. This can also be selected manually by running `az login --use-device-code`.
#### Authenticate via the Azure Developer CLI
Developers coding outside of an IDE can also use the [Azure Developer CLI](https://aka.ms/azure-dev) to authenticate. Applications using the `DefaultAzureCredential` or the `AzureDeveloperCLICredential` can use the account logged in to the Azure Developer CLI to authenticate calls in their application when running locally.
To authenticate with the Azure Developer CLI, run `azd auth login`. On a system with a default web browser, `azd` will launch the browser to authenticate. On systems without a default web browser, run `azd auth login --use-device-code` to use the device code authentication flow.
## Key concepts
### Credentials
A credential is a type which contains or can obtain the data needed for a
service client to authenticate requests. Service clients across the Azure SDK
accept a credential instance when they are constructed, and use that credential
to authenticate requests.
The `azidentity` module focuses on OAuth authentication with Microsoft Entra ID. It offers a variety of credential types capable of acquiring a Microsoft Entra access token. See [Credential Types](#credential-types "Credential Types") for a list of this module's credential types.
### DefaultAzureCredential
`DefaultAzureCredential` is appropriate for most apps that will be deployed to Azure. It combines common production credentials with development credentials. It attempts to authenticate via the following mechanisms in this order, stopping when one succeeds:
![DefaultAzureCredential authentication flow](img/mermaidjs/DefaultAzureCredentialAuthFlow.svg)
1. **Environment** - `DefaultAzureCredential` will read account information specified via [environment variables](#environment-variables) and use it to authenticate.
1. **Workload Identity** - If the app is deployed on Kubernetes with environment variables set by the workload identity webhook, `DefaultAzureCredential` will authenticate the configured identity.
1. **Managed Identity** - If the app is deployed to an Azure host with managed identity enabled, `DefaultAzureCredential` will authenticate with it.
1. **Azure CLI** - If a user or service principal has authenticated via the Azure CLI `az login` command, `DefaultAzureCredential` will authenticate that identity.
1. **Azure Developer CLI** - If the developer has authenticated via the Azure Developer CLI `azd auth login` command, the `DefaultAzureCredential` will authenticate with that account.
> Note: `DefaultAzureCredential` is intended to simplify getting started with the SDK by handling common scenarios with reasonable default behaviors. Developers who want more control or whose scenario isn't served by the default settings should use other credential types.
## Managed Identity
`DefaultAzureCredential` and `ManagedIdentityCredential` support
[managed identity authentication](https://docs.microsoft.com/azure/active-directory/managed-identities-azure-resources/overview)
in any hosting environment which supports managed identities, such as (this list is not exhaustive):
* [Azure App Service](https://docs.microsoft.com/azure/app-service/overview-managed-identity)
* [Azure Arc](https://docs.microsoft.com/azure/azure-arc/servers/managed-identity-authentication)
* [Azure Cloud Shell](https://docs.microsoft.com/azure/cloud-shell/msi-authorization)
* [Azure Kubernetes Service](https://docs.microsoft.com/azure/aks/use-managed-identity)
* [Azure Service Fabric](https://docs.microsoft.com/azure/service-fabric/concepts-managed-identity)
* [Azure Virtual Machines](https://docs.microsoft.com/azure/active-directory/managed-identities-azure-resources/how-to-use-vm-token)
## Examples
- [Authenticate with DefaultAzureCredential](#authenticate-with-defaultazurecredential "Authenticate with DefaultAzureCredential")
- [Define a custom authentication flow with ChainedTokenCredential](#define-a-custom-authentication-flow-with-chainedtokencredential "Define a custom authentication flow with ChainedTokenCredential")
- [Specify a user-assigned managed identity for DefaultAzureCredential](#specify-a-user-assigned-managed-identity-for-defaultazurecredential)
### Authenticate with DefaultAzureCredential
This example demonstrates authenticating a client from the `armresources` module with `DefaultAzureCredential`.
```go
cred, err := azidentity.NewDefaultAzureCredential(nil)
if err != nil {
// handle error
}
client := armresources.NewResourceGroupsClient("subscription ID", cred, nil)
```
### Specify a user-assigned managed identity for DefaultAzureCredential
To configure `DefaultAzureCredential` to authenticate a user-assigned managed identity, set the environment variable `AZURE_CLIENT_ID` to the identity's client ID.
### Define a custom authentication flow with `ChainedTokenCredential`
`DefaultAzureCredential` is generally the quickest way to get started developing apps for Azure. For more advanced scenarios, `ChainedTokenCredential` links multiple credential instances to be tried sequentially when authenticating. It will try each chained credential in turn until one provides a token or fails to authenticate due to an error.
The following example demonstrates creating a credential, which will attempt to authenticate using managed identity. It will fall back to authenticating via the Azure CLI when a managed identity is unavailable.
```go
managed, err := azidentity.NewManagedIdentityCredential(nil)
if err != nil {
// handle error
}
azCLI, err := azidentity.NewAzureCLICredential(nil)
if err != nil {
// handle error
}
chain, err := azidentity.NewChainedTokenCredential([]azcore.TokenCredential{managed, azCLI}, nil)
if err != nil {
// handle error
}
client := armresources.NewResourceGroupsClient("subscription ID", chain, nil)
```

|variable name|value
|-|-
|`AZURE_CLIENT_ID`|ID of a Microsoft Entra application
|`AZURE_USERNAME`|a username (usually an email address)
|`AZURE_PASSWORD`|that user's password
Configuration is attempted in the above order. For example, if values for a
client secret and certificate are both present, the client secret will be used.
## Token caching
Token caching is an `azidentity` feature that allows apps to:
* Cache tokens in memory (default) or on disk (opt-in).
* Improve resilience and performance.
* Reduce the number of requests made to Microsoft Entra ID to obtain access tokens.
For more details, see the [token caching documentation](https://aka.ms/azsdk/go/identity/caching).
## Troubleshooting
### Error Handling
Credentials return an `error` when they fail to authenticate or lack data they require to authenticate. For guidance on resolving errors from specific credential types, see the [troubleshooting guide](https://aka.ms/azsdk/go/identity/troubleshoot).
For more details on handling specific Microsoft Entra errors, see the Microsoft Entra [error code documentation](https://learn.microsoft.com/azure/active-directory/develop/reference-error-codes).
### Logging
This module uses the classification-based logging implementation in `azcore`. To enable console logging for all SDK modules, set `AZURE_SDK_GO_LOGGING` to `all`. Use the `azcore/log` package to control log event output or to enable logs for `azidentity` only. For example:
```go
import azlog "github.com/Azure/azure-sdk-for-go/sdk/azcore/log"
// print log output to stdout
azlog.SetListener(func(event azlog.Event, s string) {
fmt.Println(s)
})
// include only azidentity credential logs
azlog.SetEvents(azidentity.EventAuthentication)
```
Credentials log basic information only, such as `GetToken` success or failure and errors. These log entries don't contain authentication secrets but may contain sensitive information.
## Next steps
Client and management modules listed on the [Azure SDK releases page](https://azure.github.io/azure-sdk/releases/latest/go.html) support authenticating with `azidentity` credential types. You can learn more about using these libraries in their documentation, which is linked from the release page.

## Token caching in the Azure Identity client module
*Token caching* is a feature provided by the Azure Identity library that allows apps to:
- Improve their resilience and performance.
- Reduce the number of requests made to Microsoft Entra ID to obtain access tokens.
- Reduce the number of times the user is prompted to authenticate.
When an app needs to access a protected Azure resource, it typically needs to obtain an access token from Entra ID. Obtaining that token involves sending a request to Entra ID and may also involve prompting the user. Entra ID then validates the credentials provided in the request and issues an access token.
Token caching, via the Azure Identity library, allows the app to store this access token [in memory](#in-memory-token-caching), where it's accessible to the current process, or [on disk](#persistent-token-caching) where it can be accessed across application or process invocations. The token can then be retrieved quickly and easily the next time the app needs to access the same resource. The app can avoid making another request to Entra ID, which reduces network traffic and improves resilience. Additionally, in scenarios where the app is authenticating users, token caching also avoids prompting the user each time new tokens are requested.
### In-memory token caching
*In-memory token caching* is the default option provided by the Azure Identity library. This caching approach allows apps to store access tokens in memory. With in-memory token caching, the library first determines if a valid access token for the requested resource is already stored in memory. If a valid token is found, it's returned to the app without the need to make another request to Entra ID. If a valid token isn't found, the library will automatically acquire a token by sending a request to Entra ID. The in-memory token cache provided by the Azure Identity library is thread-safe.
**Note:** When Azure Identity library credentials are used with Azure service libraries (for example, Azure Blob Storage), the in-memory token caching is active in the `Pipeline` layer as well. All `TokenCredential` implementations are supported there, including custom implementations external to the Azure Identity library.
#### Caching cannot be disabled
As there are many levels of caching, it's not possible disable in-memory caching. However, the in-memory cache may be cleared by creating a new credential instance.
### Persistent token caching
> Only azidentity v1.5.0-beta versions support persistent token caching
*Persistent disk token caching* is an opt-in feature in the Azure Identity library. The feature allows apps to cache access tokens in an encrypted, persistent storage mechanism. As indicated in the following table, the storage mechanism differs across operating systems.
| Operating system | Storage mechanism |
|------------------|---------------------------------------|
| Linux | kernel key retention service (keyctl) |
| macOS | Keychain |
| Windows | DPAPI |
By default the token cache will protect any data which is persisted using the user data protection APIs available on the current platform.
However, there are cases where no data protection is available, and applications may choose to allow storing the token cache in an unencrypted state by setting `TokenCachePersistenceOptions.AllowUnencryptedStorage` to `true`. This allows a credential to fall back to unencrypted storage if it can't encrypt the cache. However, we do not recommend using this storage method due to its significantly lower security measures. In addition, tokens are not encrypted solely to the current user, which could potentially allow unauthorized access to the cache by individuals with machine access.
With persistent disk token caching enabled, the library first determines if a valid access token for the requested resource is already stored in the persistent cache. If a valid token is found, it's returned to the app without the need to make another request to Entra ID. Additionally, the tokens are preserved across app runs, which:
- Makes the app more resilient to failures.
- Ensures the app can continue to function during an Entra ID outage or disruption.
- Avoids having to prompt users to authenticate each time the process is restarted.
>IMPORTANT! The token cache contains sensitive data and **MUST** be protected to prevent compromising accounts. All application decisions regarding the persistence of the token cache must consider that a breach of its content will fully compromise all the accounts it contains.
#### Example code
See the [package documentation](https://pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/azidentity@v1.5.0-beta.1#pkg-overview) for code examples demonstrating how to configure persistent caching and access cached data.
### Credentials supporting token caching
The following table indicates the state of in-memory and persistent caching in each credential type.
**Note:** In-memory caching is activated by default. Persistent token caching needs to be enabled as shown in [this example](https://pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/azidentity@v1.5.0-beta.1#example-package-PersistentCache).

## Handle azidentity errors
Any service client method that makes a request to the service may return an error due to authentication failure. This is because the credential authenticates on the first call to the service and on any subsequent call that needs to refresh an access token. Authentication errors include a description of the failure and possibly an error message from Microsoft Entra ID. Depending on the application, these errors may or may not be recoverable.
### Permission issues
Service client errors with a status code of 401 or 403 often indicate that authentication succeeded but the caller doesn't have permission to access the specified API. Check the service documentation to determine which RBAC roles are needed for the request, and ensure the authenticated user or service principal has the appropriate role assignments.
## Find relevant information in errors
Authentication errors can include responses from Microsoft Entra ID and often contain information helpful in diagnosis. Consider the following error message:
```
ClientSecretCredential authentication failed
POST https://login.microsoftonline.com/3c631bb7-a9f7-4343-a5ba-a615913/oauth2/v2.0/token

}
--------------------------------------------------------------------------------
```
This error contains several pieces of information:
- __Failing Credential Type__: The type of credential that failed to authenticate. This can be helpful when diagnosing issues with chained credential types such as `DefaultAzureCredential` or `ChainedTokenCredential`.
- __Microsoft Entra ID Error Code and Message__: The error code and message returned by Microsoft Entra ID. This can give insight into the specific reason the request failed. For instance, in this case authentication failed because the provided client secret is incorrect. [Microsoft Entra ID documentation](https://learn.microsoft.com/azure/active-directory/develop/reference-error-codes#aadsts-error-codes) has more information on AADSTS error codes.
- __Correlation ID and Timestamp__: The correlation ID and timestamp identify the request in server-side logs. This information can be useful to support engineers diagnosing unexpected Microsoft Entra failures.
### Enable and configure logging
`azidentity` provides the same logging capabilities as the rest of the Azure SDK. The simplest way to see the logs to help debug authentication issues is to print credential logs to the console.
```go
import azlog "github.com/Azure/azure-sdk-for-go/sdk/azcore/log"
// print log output to stdout
azlog.SetListener(func(event azlog.Event, s string) {
fmt.Println(s)
})
// include only azidentity credential logs
azlog.SetEvents(azidentity.EventAuthentication)
```
