Sometimes, when you try to attach a legitimate character to your account, it fails due to username/password error. This is a bug, but there is a workaround :) Login to/logout from the game. Wait 20 minutes. Try attaching again.
The reason for this is that the pool for character attachment only keeps recent/active characters, but the pool itself updates once every 20-30 minutes.

But all attached characters will still point to old/obsolete/dead characters :(
