azure.identity.aio package¶

Credentials for asynchronous Azure SDK clients.

class azure.identity.aio.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.

async close()[source]¶: Close the credential’s transport session.

async 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.

class azure.identity.aio.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.

async close()[source]¶: Calling this method is unnecessary

async 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

CredentialUnavailableError – the credential was unable to invoke the Azure CLI.
ClientAuthenticationError – the credential invoked the Azure CLI but didn’t receive an access token.

class azure.identity.aio.AzurePowerShellCredential[source]¶

Authenticates by requesting a token from Azure PowerShell.

This requires previously logging in to Azure via “Connect-AzAccount”, and will use the currently logged in identity.

async close() → None [source]¶: Calling this method is unnecessary

async 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

CredentialUnavailableError – the credential was unable to invoke Azure PowerShell, or no account is authenticated
ClientAuthenticationError – the credential invoked Azure PowerShell but didn’t receive an access token

class azure.identity.aio.CertificateCredential(tenant_id: str, client_id: str, certificate_path: Optional[str] = None, **kwargs: Any)[source]¶

Authenticates as a service principal using a certificate.

The certificate must have an RSA private key, because this credential signs assertions using RS256.

See Azure Active Directory documentation for more information on configuring certificate authentication: https://docs.microsoft.com/azure/active-directory/develop/active-directory-certificate-credentials#register-your-certificate-with-microsoft-identity-platform

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. If not provided, certificate_data is required.

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.
certificate_data (bytes) – the bytes of a certificate in PEM format, including the private key
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.
cache_persistence_options (TokenCachePersistenceOptions) – configuration for persistent token caching. If unspecified, the credential will cache tokens in memory.

async close()[source]¶: Close the credential’s transport session.

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

class azure.identity.aio.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:

A service principal configured by environment variables. See EnvironmentCredential for more details.
An Azure managed identity. See ManagedIdentityCredential for more details.
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.
The user currently signed in to Visual Studio Code.
The identity currently logged in to the Azure CLI.
The identity currently logged in to Azure PowerShell.

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_powershell_credential (bool) – Whether to exclude Azure PowerShell. Defaults to False.
exclude_visual_studio_code_credential (bool) – Whether to exclude stored credential from VS Code. Defaults to False.
exclude_managed_identity_credential (bool) – Whether to exclude managed identity from the credential. Defaults to False.
exclude_shared_token_cache_credential (bool) – Whether to exclude the shared token cache. Defaults to False.
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.
