Thought I'd share in case it might help others. Like other posts, I've had this message popping up and I've tried known & working GM/Chevy passwords and PINs, but they wouldn't take. I should have noticed this, but the password prompt pops up when using my wife's User/Profile. So for those that swear they're using the correct password (and have multiple users), make sure you're under the right profile in Users.
