Is having Apple ID sign-in enough for Appstore review?

We'll be switching our application from being available for anonymous users to requiring login.

We only have social logins so no email + pw method. FB, Google and as per Appstore requirements Apple ID.

I know that the review process requires testers to be able to login, but I couldn't find any concrete information if having Apple ID is enough?

I also couldn't find a way to create test accounts for Apple ID production mode, only for sandbox which as far as I know isn't enough for the testers as they need to be able to test the production application.
