Hi,
We're working on an Azure Function that needs to authenticate against Azure AD. User interaction is not required. We've had some discussions around the best way to do this:

  1. Use the built-in App Service authentication and authorization support (https://learn.microsoft.com/en-us/azure/app-service/overview-authentication-authorization).
  2. Use Microsoft's OAuth 2.0 client credentials flow (https://learn.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-client-creds-grant-flow).

We're looking at #2 as it seems easier to implement, however I'm not convinced it's necessarily the best way forward. Please advise the best way to authenticate against Azure AD in this scenario.

Thank you
