Skipped verification during update, how do I verify the iPad now?

I ran through the 10.0,2 update on my iPad. During restart, it asked for my Apple verification password, that I didn't remember since it was stored in a locker on... duh... the iPad.

I got my password, but I don't know how to go back and do whatever verification I need to do. Or do I need to do anything?

Thx!
