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/en-us/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). KnownAuthorities 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.

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.

Note

This method is called by Azure SDK clients. It isn’t intended for use in application code.

Parameters

scopes (str) – desired scopes for the access token

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.

Keyword Arguments

executor (Executor) – An Executor instance used to execute asynchronous calls
loop – An event loop on which to schedule network I/O. If not provided, the currently running loop will be used.

class azure.identity.aio.CertificateCredential(tenant_id, client_id, certificate_path, **kwargs)[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). KnownAuthorities 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.

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

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

Asynchronously request an access token for scopes.

Note

This method is called by Azure SDK clients. It isn’t intended for use in application code.

Parameters: scopes (str) – desired scopes for the token
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.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

tenant_id (str) – ID of the service principal’s tenant. Also called its ‘directory’ ID.
client_id (str) – the service principal’s client ID
client_secret (str) – one of the service principal’s client secrets

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). KnownAuthorities defines authorities for other clouds.

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

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

Asynchronously request an access token for scopes.

Note

This method is called by Azure SDK clients. It isn’t intended for use in application code.

Parameters: scopes (str) – desired scopes for the token
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.DefaultAzureCredential(**kwargs)[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.

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). KnownAuthorities defines authorities for other clouds. Managed identities ignore this because they reside in a single cloud.
exclude_environment_credential (bool) – Whether to exclude a service principal configured by environment variables from the credential. 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.
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.

async close()¶: Close the transport sessions of all credentials in the chain.

async get_token(*scopes: str, **kwargs: Any)[source]¶

Asynchronously request an access token for scopes.

Note

This method is called by Azure SDK clients. It isn’t intended for use in application code.

Parameters: scopes (str) – desired scopes for the token
Raises: ClientAuthenticationError – authentication failed. The exception has a message attribute listing each authentication attempt and its error message.

class azure.identity.aio.EnvironmentCredential(**kwargs: Any)[source]¶

A credential configured by environment variables.

This credential is capable of authenticating as a service principal using a client secret or a certificate, or as a user with a username and password. Configuration is attempted in this order, using these environment variables:

Service principal with secret:

AZURE_TENANT_ID: ID of the service principal’s tenant. Also called its ‘directory’ ID.
AZURE_CLIENT_ID: the service principal’s client ID
AZURE_CLIENT_SECRET: one of the service principal’s client secrets

Service principal with certificate:

AZURE_TENANT_ID: ID of the service principal’s tenant. Also called its ‘directory’ ID.
AZURE_CLIENT_ID: the service principal’s client ID
AZURE_CLIENT_CERTIFICATE_PATH: path to a PEM-encoded certificate file including the private key The certificate must not be password-protected.

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

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

Asynchronously request an access token for scopes.

Note

This method is called by Azure SDK clients. It isn’t intended for use in application code.

Parameters: scopes (str) – desired scopes for the token
Return type: azure.core.credentials.AccessToken
Raises: CredentialUnavailableError – environment variable configuration is incomplete

class azure.identity.aio.ManagedIdentityCredential(**kwargs: Any)[source]¶

Authenticates with an Azure managed identity in any hosting environment which supports managed identities.

See the Azure Active Directory documentation for more information about managed identities: https://docs.microsoft.com/en-us/azure/active-directory/managed-identities-azure-resources/overview

Keyword Arguments: client_id (str) – ID of a user-assigned identity. Leave unspecified to use a system-assigned identity.

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

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

Asynchronously request an access token for scopes.

Note

This method is called by Azure SDK clients. It isn’t intended for use in application code.

Parameters: scopes (str) – desired scopes for the token
Return type: azure.core.credentials.AccessToken
Raises: CredentialUnavailableError – managed identity isn’t available in the hosting environment

class azure.identity.aio.ChainedTokenCredential(*credentials: AsyncTokenCredential)[source]¶

A sequence of credentials that is itself a credential.

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.AsyncTokenCredential) – credential instances to form the chain

async close()[source]¶: Close the transport sessions of all credentials in the chain.

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

Asynchronously request a token from each credential, in order, returning the first token received.

If no credential provides a token, raises azure.core.exceptions.ClientAuthenticationError with an error message from each credential.

Note

This method is called by Azure SDK clients. It isn’t intended for use in application code.

Parameters: scopes (str) – desired scopes for the token
Raises: ClientAuthenticationError – no credential in the chain provided a token

class azure.identity.aio.SharedTokenCacheCredential(username=None, **kwargs)[source]¶

Authenticates using tokens in the local cache shared between Microsoft applications.

Parameters

username (str) – Username (typically an email address) of the user to authenticate as. This is required because the local cache may contain tokens for multiple identities.

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). KnownAuthorities defines authorities for other clouds.
tenant_id (str) – an Azure Active Directory tenant ID. Used to select an account when the cache contains tokens for multiple identities.

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

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

Get an access token for scopes from the shared cache.

If no access token is cached, attempt to acquire one using a cached refresh token.

Note

This method is called by Azure SDK clients. It isn’t intended for use in application code.

Parameters

scopes (str) – desired scopes for the token

Return type

azure.core.credentials.AccessToken

Raises

CredentialUnavailableError – the cache is unavailable or contains insufficient user information
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.

static supported()¶

Whether the shared token cache is supported on the current platform.

Return type: bool
