Why does Google Play Games keep asking me to sign in?
The error may simply be a sign-in issue, which sometimes occurs when the Play Store is updated. The first trick is to go into your phone's main Settings menu and then Accounts & sync and simply remove the Google account that is getting the "authentication is required" error.
