Repeatedly request to Register Dual Factor Authentication on each login

Question

I registered dual factor authentication for a microsoft 365 account on the first login, using Microsoft Authenticator app and phone.

However on each subsequent login, I'm still asked to register dual factor authentication. I have done this at least four times with Microsfot Authenticator app, tried twice to use google authenticator. I restarted my computer and mobile phone, the problem persists.

Would you please help?

Are you admin?

If so, admin MFA issue only phone support can help and ask them to escalate your issue to the data protection team.
