I think it should be ManagedIdentityCredential: ManagedIdentityCredential: attempts to authenticate using a managed identity that is assigned to the deployment environment (if any). DefaultAzureCredential can not be, since only one type of authentication is allowed. ChainedTokenCredential could work if there is only one authentication type is specified in code.

Agree, the paragraph "Access to Azure App Configuration has been configured to use the identity of the web app for authentication. Security requirements specify that no other authentication systems must be used." is there to coax us into not picking DefaultAzureCredential.

I disagree. DefaultAzureCredential allows other auth methods as well, for instance when developing locally. Only ManagedIdentityCredential ensures only the identity of the app can be used for authentication

I think it should be DefaultAzureCredential. Check DefaultAzureCredential section at https://learn.microsoft.com/en-us/python/api/overview/azure/identity-readme?view=azure-python DefaultAzureCredential is appropriate for most applications which will run in the Azure Cloud because it combines common production credentials with development credentials Managed Identity - If the application is deployed to an Azure host with Managed Identity enabled, DefaultAzureCredential will authenticate with it.

I disagree, if they used options (https://docs.microsoft.com/en-us/dotnet/api/azure.identity.defaultazurecredentialoptions?view=azure-dotnet-preview) they could exclude unwanted auth methods, but it's not in the code. Otherwise "It is not always clear what authentication method got executed". Question states that "configured to use the identity" so I think it's ManagedIdentityCredential in place of azure default.

JamieS you are right. It should be ManagedIdentityCredential. I overlooked .. "Security requirements specify that no other authentication systems must be used".

ManagedIdentityCredential according to the following link : https://learn.microsoft.com/en-us/python/api/azure-identity/azure.identity.managedidentitycredential?view=azure-python We use ManagedIdentityCredential with apps or resources that support ManagedIdentityCredential.

This question is not updated with the latest Microsoft docs. The 2nd and 4th answers are not correct, and are not present in DDL. Here the right Python code: from azure.identity import DefaultAzureCredential from azure.appconfiguration import AzureAppConfigurationClient credential = DefaultAzureCredential() client = AzureAppConfigurationClient(base_url="your_endpoint_url", credential=credential) https://learn.microsoft.com/en-us/python/api/overview/azure/appconfiguration-readme?view=azure-python#create-a-client

To load configuration data from Azure App Configuration using the identity of the web app for authentication, you would typically use the ManagedIdentityCredential class for authentication. Here's how you should complete the code: from azure.identity import ManagedIdentityCredential from azure.appconfiguration import AzureAppConfigurationClient credential = ManagedIdentityCredential() client = AzureAppConfigurationClient(base_url="your_endpoint_url", credential=credential)

DefaultAzureCredentials will try different authentication, ie. it will use AZ, Visual Studio, ManagedIdentity, and so on until one succeeds

Note that the DefaultAzureCredential is used to authenticate using the identity of the web app. This credential provider tries multiple authentication methods (e.g. environment variables, Azure Managed Identity, Azure CLI) until it finds a suitable one. In this way, you can ensure that no other authentication systems are used Above ans are correct.

It should be ManagedIdentityCredential. Managed identity authentication is supported via either the DefaultAzureCredential or the ManagedIdentityCredential directly for the following Azure services: Example: from azure.identity import ManagedIdentityCredential from azure.keyvault.secrets import SecretClient credential = ManagedIdentityCredential() client = SecretClient("https://my-vault.vault.azure.net", credential) Reference: https://github.com/Azure/azure-sdk-for-python/tree/azure-appconfiguration_1.4.0/sdk/identity/azure-identity
