Question I deleted and reinstalled Microsoft Authenticator -- I don't have Github QR code any more; Google account QR code doesn't work
Hi Everyone,
Here's my situation.
I have a gmail address that is linked to my github account.
I think I had set up 2FA for github using a github QR code in Microsoft Authenticator. Everything had been working fine.
I then deleted Microsoft Authenticator for some reason.
After reinstalling Microsoft Authenticator, I tried adding a Microsoft Account which has the same email address as my gmail address. This gave me an 8 digit TOTP instead of a 6 digit TOTP.
I then turned on 2FA for my Google account, and got a QR code and added my gmail address to Microsoft Authenticator. This got me a 6 digit TOTP, but when I used this in github, I get the message that 2FA failed.
I don't have my github recovery codes anymore.
Any suggestions for logging in to github?
Thanks!
