TL;DR, my computer broke because I spilled water onto it. I got a new phone recently and my number was changed, so I couldn’t use that to log back in with 2-step verification, and I tried send it to my alternate email instead. It says I have to “wait 24 hours” but I never get the fucking verification email so apparently I have lost my email account and everything attached to it.
Too late for OP, but for everyone that can get into their accounts but doesn’t know what the backup codes are, go here, select ‘backup codes’ and then keep them in a safe place.
