sign in to appleid.apple.com or Use Another Account
When I get to the login window, I'm asked if I want to sign in with my Apple ID and then password. If I put in the password it won't let me log in with that password.
Go back and choose another account: Using the other account, I use the same Apple ID as "sign in to appleid.apple.com". I then use the same password that was previously used in appleid.apple.com, except this time I log in.
What could be the possible reasons I can't use appleid.apple.com, but using the other account option using the same user name and password I can log in.
