Answer 2

Something else to try is a different authenticator. Dare I say try using Google Authenticator as a a workaround\troubleshooting step. Just in case conditional access is causing the issue.

I think the Microsoft authenticator works slightly differently when you are using a Microsoft account and is trying to log you in with your corporate Microsoft account.

This allows you to receive popups that you can just “approve” the request which I think is called “Simple Approvals” in MFA terminology. This is different to one time passwords (OTP).

I can remember having all sorts of issues with conditional access when trying to connect to a suppliers Teams site as a guest using my corporate Microsoft account and the Microsoft authenticator on my personal device. Setting up the authentication using the Google app resolved all of this, as it defaulted back to OTP where the conditional access rules no longer apply.

You can't force a connection to use OTP within the Microsoft authenticator app (as far as I'm aware).

Answer 3

Yes it's right we can also try another app. I also tried google authenticator but it's saying wrong code or wrong otp. I even tried multiple times but stills same. I also tried the key and account code but still not worked, it said wrong code
