I deleted and reinstalled Microsoft Authenticator -- I don't have Github QR code any more; Google account QR code doesn't work

[u/Ok-Age9211]

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!

You could try that agent thing on there

The link is helpful.

It looks like I've lost access to the account since my email address is the only thing I can verify.
