How Do I Regain Access to My Account After Losing Access to Microsoft Authenticator?

Question

I have a Microsoft Office Business Basic account. I am the admin using ******@accessdzn. Recently, I switched to a new mobile phone and lost access to my Microsoft Authenticator app.

Now, every time I try to log in, Microsoft asks for a verification code from the Authenticator app, which I no longer have access to. I’m stuck in an endless MFA loop—I need the app to verify my identity, but I can’t access the app without verifying my identity first.

I’ve tried account recovery, and while it allows me to reset my password, I still can’t log into my account because I’m always prompted for the Authenticator code. I also can’t disable two-factor authentication (2FA) since I need to verify my identity using the same app I no longer have.

I urgently need help regaining full access to my account.

My recovery email is: ****@gmail.com

Any guidance would be greatly appreciated!
