Microsoft does this all the time where they will lock you out of an account and make it near impossible for you to recover even when you still have access to the email address and password.
So disappointing since it was my only point of contact with lots of old friends.
To be fair, they want me to email pictures of my driver's license to recover the account, which they pinky-promise they'll delete afterwards. I'm not willing to do that, given I didn't have to provide any ID to sign up in the first place. So now I'm looking into having this form they sent to me notorized so I can get access back. What a mess.
Edit: nevermind, I'm sure I'm wrong about this, and it's offtopic anyway. Apologies!
Reset codes, as in some entities will provide you with a page/image/etc. with ~10 codes on it when you enable 2FA, which can each be used once in place of the code generated by the 2FA token, letting you get into the account to, e.g. set up a new 2FA token/method.
