MFA authenticator loop as sole admin on microsoft 365 business

Question

Hello,

I am the only admin on my MS 365 Business Basic subscription. I cannot get into admin because it asks me to use the Authenticator app. However, while my admin email shows in the Authenticator app, it tells me the MFA is not set up. When I click to set that up, it asks me to login to my admin and requests verification through the MFA, which as I said, isn’t set up.

I am stuck in a loop and cannot get into my admin center.

I don’t think I’ve changed my phone, but maybe app updates have caused the app updates have removed the MFA set up? This definitely happened for my other (non-admin) user profile within the company, so I am not able to login to that either since I updated the Authenticator app. BUT for the admin account I don’t even ever remember setting up the Authenticator. It definitely wasn’t in the previous version of the Authenticator app.

So how do I get out of the Authenticator loop as the sole admin in the Microsoft 365 Business Basic account?

Thank you

Hi SisterKatya,

If you are the only admin then I would recommend you to follow some of faqs for similar issue over here - common-problems-with-two-step-verification-for-a-work-or-school-account-63acbb9b-16a1-47b9-8619-6a865e8071a5

If that does not work you will have to raise a support call with Microsoft to reset the MFA.
