the github account uses DUO for two-factor authentication, which is required for each login. The user name of github has been changed before. Today, when I change my phone, I re-scan the QR code of my account with the DUO on the new phone, and then delete the old phone software. But it is found that the CAPTCHA on the new phone is invalid, and I don"t know what"s going on. Is there any other way to log in to the account?
I emailed back to support@github.com, saying that I should find recover code, but the previous recover code, I found was also invalid.
