 ### Use DefaultAzureCredential
 
-The `DefaultAzureCredential` is a preconfigured [chain of token credentials](/dotnet/azure/sdk/authentication/credential-chains.md#defaultazurecredential-overview) that automatically attempts an ordered sequence of the most common authentication methods. Using the `DefaultAzureCredential` allows you to keep the same code in both local development and Azure environments. However, it's important to know which credential is being used in each environment, as you need to grant the appropriate roles for authorization to work. For example, authorize your own account when you expect the `DefaultAzureCredential` to fall back to your user identity during local development. Similarly, enable managed identity in Azure Functions and assign it the necessary role when you expect the `DefaultAzureCredential` to fall back to the `ManagedIdentityCredential` when your Function App runs in Azure.

+# Add managed identities for Azure App Configuration
 
 This article shows you how to create a managed identity for Azure App Configuration. A managed identity from Microsoft Entra ID allows Azure App Configuration to easily access other Microsoft Entra protected resources. The identity is managed by the Azure platform. It doesn't require you to provision or rotate any secrets. For more about managed identities in Microsoft Entra ID, see [Managed identities for Azure resources](../active-directory/managed-identities-azure-resources/overview.md).
