was able to reset password on my computer during that process I received a verification code. When I tried to use it on my ipad it said it was invalid. How do I get another verification code?

See if anything here helps.  If necessary, you can use account recovery as explained in the link at bottom of the article.

A Few Thoughts:

I. On your iPnone:

Reset Reset Location & Privacy Settings:

It will reset its prompting, prompting you once more, hopefully not going through a loop this time.

1. Go To: Settings
2. Tap: General
3. Tap: Reset
4. Enter: your Passcode
5. Tap: Reset

II. Sign Out then Back In:

Sign out of iTunes on your Android device, then Sign back in. Do the same on your iPad, but use iCloud. Update the devices. See if it then works. Things might need to re-sync.
