FILE: sample_authentication_async.py
DESCRIPTION:
This sample demonstrates authenticating a client via:
* api key
* Microsoft Entra ID
USAGE:
python sample_authentication_async.py
Set the environment variables with your own values before running this sample:
1) AZURE_FACE_API_ENDPOINT - the endpoint to your Face resource.
The environment variable below is used for api key authentication.
2) AZURE_FACE_API_ACCOUNT_KEY - your Face API key.
The following environment variables are required for using azure-identity's DefaultAzureCredential.
For more information, refer to https://aka.ms/azsdk/python/identity/docs#azure.identity.DefaultAzureCredential
3) AZURE_TENANT_ID - the tenant ID in Microsoft Entra ID
4) AZURE_CLIENT_ID - the application (client) ID registered in the AAD tenant
5) AZURE_CLIENT_SECRET - the client secret for the registered application
