title: Why does Github 2FA recovery codes fail?
body: <p>I am officially blocked with 2FA! I cannot login to my Github account while I was able to do it before using one of the recovery codes. I changed my phone and the authentication app doesn't work on the new one. I used one of the codes before to login and it was successful but now none of the codes are working. I also don't have a recovery token. Does anyone have any idea what to do at this point?</p>
