Hello Microsoft Support / Microsoft Entra team,

I have lost access to the Microsoft Authenticator app for my account ******@loyaltradebd.com and I am unable to sign in to the Azure portal or Microsoft 365 admin center.

I am the only Global Administrator for this tenant, and I did not configure any backup authentication methods such as phone number or recovery options.

Because of this, I am locked out of the admin portal and cannot reset my MFA. I urgently need assistance to reset or disable MFA on this account to regain access.

Please let me know what information you need to verify ownership and proceed with unlocking my account.

Thank you for your support, Moazzem Hossain

    Hello MoazzemHossain,

    I see you have mentioned affected email address as ******@xxxxxx.com. When I checked on my end, I see there are multiple global administrator user accounts are there in the tenant. As you are not able to login into your work or school account due to incomplete of MFA. In this situation, you need to contact your other Global administrator to reset your MFA registration.

    Please share these steps with your other global admins to reset your MFA. I have shared more details over private message please check.

    To manage user settings, complete the following steps:

    1.Sign in to the Microsoft Entra admin center as at least an Authentication Administrator.

    2.Browse to Identity > Users > All users.

    3.Choose the user you wish to perform an action on and select Authentication methods. At the top of the window, then choose “Require re-register MFA” options for the user.

    Screenshot of manage authentication methods from the Microsoft Entra admin center. Then you can login back to any office application and register with new MFA auth method.
