I hired an app developer to build an app for me, and we're now at the final stage of development. He says he needs my Apple ID login credentials so he can publish the app through Xcode. However, I have already invited him to my Apple Developer Program account and granted him the App Developer role with the necessary permissions. Does he really need my Apple ID login credentials to publish the app, or should the permissions I already granted be sufficient? Unfortunately, Apple Support hasn't been able to answer this question.
