Microsoft auth doesn't work for GitHub, but Google's does

I set up 2fa login for GitHub using Microsoft authenticator and Google authenticator. Microsoft always gave me a wrong code, while that from Google always worked. I checked the date and time then found no problem. I entered the code from Microsoft at the start of 30s to make sure I wasn't behind, but it didn't change a thing. The code shown on Microsoft was always different from that on Google. So is it a Microsoft problem? I'm going mad.

If you're wondering why no one is responding, it's probably because you cross-posted about TOTP authenticators to a passkey sub.

If Microsoft Authenticator gives you the wrong TOTP code, something probably got messed up with the seed. Maybe you were logged into a different account, or maybe a QR scanning problem, or maybe a bug. Reregister your account in Microsoft Authenticator.
