Xcode 8 logs out my developer account saying "session has expired"

Question

When I am using my developer account, I am getting this message in Xcode 8.

Your session has expired. Please log in.

With another Apple ID it works. Also when logging in to developer.apple.com everything is okay; I log in without a problem. How can I fix this?

Answer 1

I just added two factor authentication to my Apple ID and Xcode was fine again. Don't know how it's related but it worked for me. Do the same.

Answer 2

As @Satam Sync suggested activation of two factor authentication seems to work. If you already use it you can try deactivate end reactivate it.

For your interest this is the support answer from Apple I received:
