## 1.14.0-beta.2 (2025-11-10)

### Breaking Changes

> These changes affect only code written against a beta version such as v1.13.0-beta.1
- `WorkloadIdentityCredential` identity binding mode is disabled by default. To enable it, set
  `WorkloadIdentityCredentialOptions.EnableAzureTokenProxy` to `true`
- Removed identity binding mode support from `DefaultAzureCredential`. To use this feature, use
  `WorkloadIdentityCredential` directly instead and set
  `WorkloadIdentityCredentialOptions.EnableAzureTokenProxy` to `true`

### Bugs Fixed

- `AzureCLICredential` quoted arguments incorrectly on Windows

## 1.13.1 (2025-11-10)

### Bugs Fixed

- `AzureCLICredential` quoted arguments incorrectly on Windows

## 1.14.0-beta.1 (2025-10-07)

### Features Added

- Restored the `WorkloadIdentityCredential` identity binding mode support removed in v1.13.0

## 1.13.0 (2025-10-07)

### Features Added

- Added `AzurePowerShellCredential`, which authenticates as the identity logged in to Azure PowerShell
  (thanks [ArmaanMcleod](https://github.com/ArmaanMcleod))
- When `AZURE_TOKEN_CREDENTIALS` is set to `ManagedIdentityCredential`, `DefaultAzureCredential` behaves the same as
  does `ManagedIdentityCredential` when used directly. It doesn't apply special retry configuration or attempt to
  determine whether IMDS is available. ([#25265](https://github.com/Azure/azure-sdk-for-go/issues/25265))

### Breaking Changes

* Removed the `WorkloadIdentityCredential` support for identity binding mode added in v1.13.0-beta.1.
  It will return in v1.14.0-beta.1

## 1.13.0-beta.1 (2025-09-17)

### Features Added

- Added `AzurePowerShellCredential`, which authenticates as the identity logged in to Azure PowerShell
  (thanks [ArmaanMcleod](https://github.com/ArmaanMcleod))
- `WorkloadIdentityCredential` supports identity binding mode ([#25056](https://github.com/Azure/azure-sdk-for-go/issues/25056))

## 1.12.0 (2025-09-16)

### Features Added
- Added `DefaultAzureCredentialOptions.RequireAzureTokenCredentials`. `NewDefaultAzureCredential` returns an
  error when this option is true and the environment variable `AZURE_TOKEN_CREDENTIALS` has no value.

### Other Changes
- `AzureDeveloperCLICredential` no longer hangs when AZD_DEBUG is set
- `GetToken` methods of `AzureCLICredential` and `AzureDeveloperCLICredential` return an error when
  `TokenRequestOptions.Claims` has a value because these credentials can't acquire a token in that
  case. The error messages describe the action required to get a token.

## 1.11.0 (2025-08-05)

### Other Changes
- `DefaultAzureCredential` tries its next credential when a dev tool credential such as
  `AzureCLICredential` returns an error

## 1.11.0-beta.1 (2025-07-15)

### Features Added
- `DefaultAzureCredential` allows selecting one of its credential types by name via environment variable
  `AZURE_TOKEN_CREDENTIALS`. It will use only the selected type at runtime. For example, set
  `AZURE_TOKEN_CREDENTIALS=WorkloadIdentityCredential` to have `DefaultAzureCredential` use only
  `WorkloadIdentityCredential`.

### Other Changes
- By default, `ManagedIdentityCredential` retries IMDS requests for a maximum of ~70 seconds as recommended
  in IMDS documentation. In previous versions, it would stop retrying after ~54 seconds by default.

## 1.10.1 (2025-06-10)

### Bugs Fixed
- `AzureCLICredential` and `AzureDeveloperCLICredential` could wait indefinitely for subprocess output

## 1.10.0 (2025-05-14)

### Features Added
- `DefaultAzureCredential` reads environment variable `AZURE_TOKEN_CREDENTIALS` to enable a subset of its credentials:
  - `dev` selects `AzureCLICredential` and `AzureDeveloperCLICredential`
  - `prod` selects `EnvironmentCredential`, `WorkloadIdentityCredential` and `ManagedIdentityCredential`

## 1.9.0 (2025-04-08)

### Features Added
* `GetToken()` sets `AccessToken.RefreshOn` when the token provider specifies a value

### Other Changes
* `NewManagedIdentityCredential` logs the configured user-assigned identity, if any
* Deprecated `UsernamePasswordCredential` because it can't support multifactor
  authentication (MFA), which Microsoft Entra ID requires for most tenants. See
  https://aka.ms/azsdk/identity/mfa for migration guidance.
* Updated dependencies

## 1.8.2 (2025-02-12)

### Other Changes
* Upgraded dependencies

## 1.8.1 (2025-01-15)

### Bugs Fixed
* User credential types inconsistently log access token scopes
* `DefaultAzureCredential` skips managed identity in Azure Container Instances
* Credentials having optional tenant IDs such as `AzureCLICredential` and
  `InteractiveBrowserCredential` require setting `AdditionallyAllowedTenants`
  when used with some clients

### Other Changes
* `ChainedTokenCredential` and `DefaultAzureCredential` continue to their next
  credential after `ManagedIdentityCredential` receives an unexpected response
  from IMDS, indicating the response is from something else such as a proxy

## 1.8.0 (2024-10-08)

### Other Changes
* `AzurePipelinesCredential` sets an additional OIDC request header so that it
  receives a 401 instead of a 302 after presenting an invalid system access token
* Allow logging of debugging headers for `AzurePipelinesCredential` and include
  them in error messages

## 1.8.0-beta.3 (2024-09-17)

### Features Added
* Added `ObjectID` type for `ManagedIdentityCredentialOptions.ID`

### Other Changes
* Removed redundant content from error messages

## 1.8.0-beta.2 (2024-08-06)

### Breaking Changes
* `NewManagedIdentityCredential` now returns an error when a user-assigned identity
  is specified on a platform whose managed identity API doesn't support that.
  `ManagedIdentityCredential.GetToken()` formerly logged a warning in these cases.
  Returning an error instead prevents the credential authenticating an unexpected
  identity, causing a client to act with unexpected privileges. The affected
  platforms are:
  * Azure Arc
  * Azure ML (when a resource ID is specified; client IDs are supported)
  * Cloud Shell
  * Service Fabric

### Other Changes
* If `DefaultAzureCredential` receives a non-JSON response when probing IMDS before
  attempting to authenticate a managed identity, it continues to the next credential
  in the chain instead of immediately returning an error.

## 1.8.0-beta.1 (2024-07-17)

### Features Added
* Restored persistent token caching feature

### Breaking Changes
> These changes affect only code written against a beta version such as v1.7.0-beta.1
* Redesigned the persistent caching API. Encryption is now required in all cases
  and persistent cache construction is separate from credential construction.
  The `PersistentUserAuthentication` example in the package docs has been updated
  to demonstrate the new API.

## 1.7.0 (2024-06-20)

### Features Added
* `AzurePipelinesCredential` authenticates an Azure Pipelines service connection with
  workload identity federation

### Breaking Changes
> These changes affect only code written against a beta version such as v1.7.0-beta.1
* Removed the persistent token caching API. It will return in v1.8.0-beta.1

## 1.7.0-beta.1 (2024-06-10)

### Features Added
* Restored `AzurePipelinesCredential` and persistent token caching API

## Breaking Changes
> These changes affect only code written against a beta version such as v1.6.0-beta.4
* Values which `NewAzurePipelinesCredential` read from environment variables in
  prior versions are now parameters
* Renamed `AzurePipelinesServiceConnectionCredentialOptions` to `AzurePipelinesCredentialOptions`

### Bugs Fixed
* Managed identity bug fixes

## 1.6.0 (2024-06-10)

### Features Added
* `NewOnBehalfOfCredentialWithClientAssertions` creates an on-behalf-of credential
  that authenticates with client assertions such as federated credentials

### Breaking Changes
> These changes affect only code written against a beta version such as v1.6.0-beta.4
* Removed `AzurePipelinesCredential` and the persistent token caching API.
  They will return in v1.7.0-beta.1

### Bugs Fixed
* Managed identity bug fixes

## 1.6.0-beta.4 (2024-05-14)

### Features Added
* `AzurePipelinesCredential` authenticates an Azure Pipeline service connection with
  workload identity federation

## 1.6.0-beta.3 (2024-04-09)

### Breaking Changes
* `DefaultAzureCredential` now sends a probe request with no retries for IMDS managed identity
  environments to avoid excessive retry delays when the IMDS endpoint is not available. This
  should improve credential chain resolution for local development scenarios.

### Bugs Fixed
* `ManagedIdentityCredential` now specifies resource IDs correctly for Azure Container Instances

## 1.5.2 (2024-04-09)

### Bugs Fixed
* `ManagedIdentityCredential` now specifies resource IDs correctly for Azure Container Instances

### Other Changes
* Restored v1.4.0 error behavior for empty tenant IDs
* Upgraded dependencies

## 1.6.0-beta.2 (2024-02-06)

### Breaking Changes
> These changes affect only code written against a beta version such as v1.6.0-beta.1
* Replaced `ErrAuthenticationRequired` with `AuthenticationRequiredError`, a struct
  type that carries the `TokenRequestOptions` passed to the `GetToken` call which
  returned the error.

### Bugs Fixed
* Fixed more cases in which credential chains like `DefaultAzureCredential`
  should try their next credential after attempting managed identity
  authentication in a Docker Desktop container

### Other Changes
* `AzureCLICredential` uses the CLI's `expires_on` value for token expiration

## 1.6.0-beta.1 (2024-01-17)

### Features Added
* Restored persistent token caching API first added in v1.5.0-beta.1
* Added `AzureCLICredentialOptions.Subscription`

## 1.5.1 (2024-01-17)

### Bugs Fixed
* `InteractiveBrowserCredential` handles `AdditionallyAllowedTenants` correctly

## 1.5.0 (2024-01-16)

> These changes affect only code written against a beta version such as v1.5.0-beta.1
* Removed persistent token caching. It will return in v1.6.0-beta.1

### Bugs Fixed
* Credentials now preserve MSAL headers e.g. X-Client-Sku

### Other Changes
* Upgraded dependencies

## 1.5.0-beta.2 (2023-11-07)

### Features Added
* `DefaultAzureCredential` and `ManagedIdentityCredential` support Azure ML managed identity
* Added spans for distributed tracing.

## 1.5.0-beta.1 (2023-10-10)

### Features Added
* Optional persistent token caching for most credentials. Set `TokenCachePersistenceOptions`
  on a credential's options to enable and configure this. See the package documentation for
  this version and [TOKEN_CACHING.md](https://aka.ms/azsdk/go/identity/caching) for more
  details.
* `AzureDeveloperCLICredential` authenticates with the Azure Developer CLI (`azd`). This
  credential is also part of the `DefaultAzureCredential` authentication flow.

## 1.4.0 (2023-10-10)

### Bugs Fixed
* `ManagedIdentityCredential` will now retry when IMDS responds 410 or 503

## 1.4.0-beta.5 (2023-09-12)

### Features Added
* Service principal credentials can request CAE tokens

### Breaking Changes
> 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))

## 1.4.0-beta.4 (2023-08-16)

### Other Changes
* Upgraded dependencies

## 1.3.0 (2023-05-09)

### Breaking Changes
> These changes affect only code written against a beta version such as v1.3.0-beta.5
* Renamed `NewOnBehalfOfCredentialFromCertificate` to `NewOnBehalfOfCredentialWithCertificate`
* Renamed `NewOnBehalfOfCredentialFromSecret` to `NewOnBehalfOfCredentialWithSecret`

### Other Changes
* Upgraded to MSAL v1.0.0

## 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
* Fixed an issue in `DefaultAzureCredential` that could cause the managed identity endpoint check to fail in rare circumstances.

## 1.3.0-beta.4 (2023-03-08)

### Features Added
* Added `WorkloadIdentityCredentialOptions.AdditionallyAllowedTenants` and `.DisableInstanceDiscovery`

### 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://learn.microsoft.com/entra/identity-platform/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

### 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

  ([#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)
