About you
Your name here is shown beside what you say. The name you sign in with cannot change, and is shown beside this one when the two differ.
Getting back in
There is no address here to send a password reset to, so these are the way back in if you forget yours. Eight codes, each good once. Keep them somewhere that is not this browser.
This is the only time these are shown. Write them down or put them somewhere safe now. Making a new set destroys this one.
