My 75 year old mother has forgotten her account info on her iPad. My wife had actually set it up for her and for years she was fine on it just to play games. Recently, for some reason, it reset itself and is now asking for the account info for logging in.. She doesn't have it. So I'm assuming it would be like if someone stole an iPad or found one, that they can't just reset the password with a new one even if you do a factory reset. So it useless now? Apple can't help. I already reached out to them.
