azure.identity package¶

Credentials for Azure SDK clients.

class azure.identity.AuthorizationCodeCredential(tenant_id, client_id, authorization_code, redirect_uri, **kwargs)[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.

get_token(*scopes, **kwargs)[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 –

class azure.identity.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. This file must not be password-protected.

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.

get_token(*scopes, **kwargs)[source]¶

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 –

class azure.identity.ChainedTokenCredential(*credentials)[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.TokenCredential) – credential instances to form the chain

get_token(*scopes, **kwargs)[source]¶

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

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 – when no credential in the chain provides a token

class azure.identity.ClientSecretCredential(tenant_id, client_id, client_secret, **kwargs)[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.

get_token(*scopes, **kwargs)[source]¶

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 –

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

get_token(*scopes, **kwargs)[source]¶

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.DeviceCodeCredential(client_id, **kwargs)[source]¶

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.

This credential doesn’t cache tokens–each get_token() call begins a new authentication flow.

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

Parameters

client_id (str) – the application’s ID

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. 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
- expires_on (datetime.datetime) the UTC time at which the code will expire
If this argument isn’t provided, the credential will print instructions to stdout.

get_token(*scopes, **kwargs)[source]¶

Request an access token for scopes.

This credential won’t cache the token. Each call begins a new authentication flow.

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 –

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

This will open a browser to a login page and listen on localhost for a request indicating authentication has completed.

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 –

Raises: ClientAuthenticationError –

class azure.identity.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 used when the local cache contains 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.

get_token(*scopes, **kwargs)[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: azure.core.exceptions.ClientAuthenticationError when the cache is unavailable or no access token can be acquired from it

static supported()¶

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

Return type: bool

class azure.identity.UsernamePasswordCredential(client_id, username, password, **kwargs)[source]¶

Authenticates a user with a username and password.

In general, Microsoft doesn’t recommend this kind of authentication, because it’s less secure than other authentication flows.

Authentication with this credential is not interactive, so it is not compatible with any form of multi-factor authentication or consent prompting. The application must already have consent from the user or a directory admin.

This credential can only authenticate work and school accounts; Microsoft accounts are not supported. See this document for more information about account types: https://docs.microsoft.com/en-us/azure/active-directory/fundamentals/sign-up-organization

username (str) – the user’s username (usually an email address)
password (str) – the user’s password

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) – tenant ID or a domain associated with a tenant. If not provided, defaults to the ‘organizations’ tenant, which supports only Azure Active Directory work or school accounts.

get_token(*scopes, **kwargs)[source]¶

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
