args
class azure.identity.AuthorizationCodeCredential(tenant_id: str, client_id: str, authorization_code: str, redirect_uri: str, **kwargs: Any)[source]

Authenticates by redeeming an authorization code previously obtained from Azure Active Directory.

See https://docs.microsoft.com/azure/active-directory/develop/v2-oauth2-auth-code-flow for more information about the authentication flow.

Parameters

  • tenant_id (str) – ID of the application’s Azure Active Directory tenant. Also called its ‘directory’ ID.

  • client_id (str) – the application’s client ID

  • authorization_code (str) – the authorization code from the user’s log-in

  • redirect_uri (str) – The application’s redirect URI. Must match the URI used to request the authorization code.

Keyword Arguments

  • authority (str) – Authority of an Azure Active Directory endpoint, for example ‘login.microsoftonline.com’, the authority for Azure Public Cloud (which is the default). AzureAuthorityHosts defines authorities for other clouds.

  • client_secret (str) – One of the application’s client secrets. Required only for web apps and web APIs.

get_token(*scopes: str, **kwargs: Any) → AccessToken[source]

Request an access token for scopes.

This method is called automatically by Azure SDK clients.

The first time this method is called, the credential will redeem its authorization code. On subsequent calls the credential will return a cached access token or redeem a refresh token, if it acquired a refresh token upon redeeming the authorization code.

Parameters

scopes (str) – desired scopes for the access token. This method requires at least one scope.

Return type

azure.core.credentials.AccessToken

Raises

ClientAuthenticationError – authentication failed. The error’s message attribute gives a reason. Any error response from Azure Active Directory is available as the error’s response attribute.

AZURE_GOVERNMENT = 'login.microsoftonline.us'
AZURE_PUBLIC_CLOUD = 'login.microsoftonline.com'
class azure.identity.AzureCliCredential[source]

Authenticates by requesting a token from the Azure CLI.

This requires previously logging in to Azure via “az login”, and will use the CLI’s currently logged in identity.

get_token(*scopes: str, **kwargs: Any) → AccessToken[source]

Request an access token for scopes.

This method is called automatically by Azure SDK clients. Applications calling this method directly must also handle token caching because this credential doesn’t cache the tokens it acquires.

Parameters

scopes (str) – desired scope for the access token. This credential allows only one scope per request.

Return type

azure.core.credentials.AccessToken

Raises
class azure.identity.CertificateCredential(tenant_id: str, client_id: str, certificate_path: str, **kwargs: Any)[source]

Authenticates as a service principal using a certificate.

Parameters

  • tenant_id (str) – ID of the service principal’s tenant. Also called its ‘directory’ ID.

  • client_id (str) – the service principal’s client ID

  • certificate_path (str) – path to a PEM-encoded certificate file including the private key.

Keyword Arguments

  • authority (str) – Authority of an Azure Active Directory endpoint, for example ‘login.microsoftonline.com’, the authority for Azure Public Cloud (which is the default). AzureAuthorityHosts defines authorities for other clouds.

  • password (str or bytes) – The certificate’s password. If a unicode string, it will be encoded as UTF-8. If the certificate requires a different encoding, pass appropriately encoded bytes instead.

  • send_certificate_chain (bool) – if True, the credential will send the public certificate chain in the x5c header of each token request’s JWT. This is required for Subject Name/Issuer (SNI) authentication. Defaults to False.

get_token(*scopes: str, **kwargs: Any) → AccessToken

Request an access token for scopes.

This method is called automatically by Azure SDK clients.

Parameters

scopes (str) – desired scopes for the access token. This method requires at least one scope.

Return type

azure.core.credentials.AccessToken

Raises
class azure.identity.ChainedTokenCredential(*credentials: TokenCredential)[source]

Its get_token() method calls get_token on each credential in the sequence, in order, returning the first valid token received.

Parameters

credentials (azure.core.credentials.TokenCredential) – credential instances to form the chain

get_token(*scopes: str, **kwargs: Any) → AccessToken[source]

Request a token from each chained credential, in order, returning the first token received.

This method is called automatically by Azure SDK clients.

Parameters

scopes (str) – desired scopes for the access token. This method requires at least one scope.

Raises

ClientAuthenticationError – no credential in the chain provided a token

class azure.identity.ClientSecretCredential(tenant_id: str, client_id: str, client_secret: str, **kwargs: Any)[source]

Authenticates as a service principal using a client ID and client secret.

Parameters

Return type

azure.core.credentials.AccessToken

Raises
class azure.identity.DefaultAzureCredential(**kwargs: Any)[source]

A default credential capable of handling most Azure SDK authentication scenarios.

The identity it uses depends on the environment. When an access token is needed, it requests one using these identities in turn, stopping when one provides a token:

  1. A service principal configured by environment variables. See EnvironmentCredential for more details.

  2. An Azure managed identity. See ManagedIdentityCredential for more details.

  3. On Windows only: a user who has signed in with a Microsoft application, such as Visual Studio. If multiple identities are in the cache, then the value of the environment variable AZURE_USERNAME is used to select which identity to use. See SharedTokenCacheCredential for more details.

  4. The user currently signed in to Visual Studio Code.

  5. The identity currently logged in to the Azure CLI.

This default behavior is configurable with keyword arguments.

Keyword Arguments

  • authority (str) – Authority of an Azure Active Directory endpoint, for example ‘login.microsoftonline.com’, the authority for Azure Public Cloud (which is the default). AzureAuthorityHosts defines authorities for other clouds. Managed identities ignore this because they reside in a single cloud.

  • exclude_cli_credential (bool) – Whether to exclude the Azure CLI from the credential. Defaults to False.

  • exclude_environment_credential (bool) – Whether to exclude a service principal configured by environment variables from the credential. Defaults to False.

  • exclude_visual_studio_code_credential (bool) – Whether to exclude stored credential from VS Code. Defaults to False.

  • exclude_shared_token_cache_credential (bool) – Whether to exclude the shared token cache. Defaults to False.

  • exclude_interactive_browser_credential (bool) – Whether to exclude interactive browser authentication (see InteractiveBrowserCredential). Defaults to True.

  • interactive_browser_tenant_id (str) – Tenant ID to use when authenticating a user through InteractiveBrowserCredential. Defaults to the value of environment variable AZURE_TENANT_ID, if any. If unspecified, users will authenticate in their home tenants.

  • managed_identity_client_id (str) – The client ID of a user-assigned managed identity. Defaults to the value of the environment variable AZURE_CLIENT_ID, if any. If not specified, a system-assigned identity will be used.

  • shared_cache_username (str) – Preferred username for SharedTokenCacheCredential. Defaults to the value of environment variable AZURE_USERNAME, if any.

  • shared_cache_tenant_id (str) – Preferred tenant for SharedTokenCacheCredential. Defaults to the value of environment variable AZURE_TENANT_ID, if any.

  • visual_studio_code_tenant_id (str) – Tenant ID to use when authenticating with VisualStudioCodeCredential.

get_token(*scopes: str, **kwargs: Any) → AccessToken[source]

Request an access token for scopes.

This method is called automatically by Azure SDK clients.

Parameters

Authenticates users through the device code flow.

When get_token() is called, this credential acquires a verification URL and code from Azure Active Directory. A user must browse to the URL, enter the code, and authenticate with Azure Active Directory. If the user authenticates successfully, the credential receives an access token.

For more information about the device code flow, see Azure Active Directory documentation: https://docs.microsoft.com/azure/active-directory/develop/v2-oauth2-device-code

Parameters

client_id (str) – client ID of the application users will authenticate to. When not specified users will authenticate to an Azure development application.

Keyword Arguments

  • authority (str) – Authority of an Azure Active Directory endpoint, for example ‘login.microsoftonline.com’, the authority for Azure Public Cloud (which is the default). AzureAuthorityHosts defines authorities for other clouds.

  • tenant_id (str) – an Azure Active Directory tenant ID. Defaults to the ‘organizations’ tenant, which can authenticate work or school accounts. Required for single-tenant applications.

  • timeout (int) – seconds to wait for the user to authenticate. Defaults to the validity period of the device code as set by Azure Active Directory, which also prevails when timeout is longer.

  • prompt_callback (Callable[str, str, datetime]) –

    A callback enabling control of how authentication instructions are presented. Must accept arguments (verification_uri, user_code, expires_on):

    • verification_uri (str) the URL the user must visit

    • user_code (str) the code the user must enter there
