Sign in to iMessage/iCloud prompt won't go away after I cancel on iPad

[iMore Question]

I keep getting a prompt to sign in to iCloud and iMessage on my iPad. It's using an old Apple ID. I've tried to reset the PW to no avail. It's the most frustrating thing....

Try both of these for a better understanding on what to do ok:

Apple ID - Apple Support

Apple ID: If you forget your password

This should get you what you need to know. Good luck.
