Azure B2C Authentication without user

Question

We use an Azure AD B2C Api. The user authentication via Angular Frontend works fine. Now, we created a separate BackgroundService project (.net core 3.0) that needs to access the api, too. The service runs without a user authentication. In a standard Azure AD Api I would authenticate the service by using ClientId and Secret.

How can I authenticate the service against the B2C Api without user authentication?

Answer 1

Client credential flow is not currently supported by Azure AD B2C. See Current limitations.
