Global Admin Locked out

Hi, I’m locked out of our company's Microsoft 365 admin account because my phone with the Authenticator app was stolen, and so I no longer have access to it.

I’m the only Global Administrator. MFA is required, and my only registered method was Microsoft Authenticator, which I can no longer use.

I know the password, but I can’t complete MFA, and I don’t have any other verification methods.

Because of this, I am unable to sign in to the Microsoft 365 admin portals to reset security information or open a support ticket.

Could a moderator please escalate this to Microsoft Support (Data Protection / Tenant Recovery) so they can verify ownership and help reset MFA registration? @VEMULA SRISAI Please help,I saw your comment on someone's post with the same issue.

Thank you

    Hello Nishtha Nagpal

    Thank you for reaching out to Microsoft Q&A.

    I understand that you're having trouble logging into the Azure portal because you haven't received the code needed in the Microsoft Authenticator App to verify your MFA.

    In this case, if there is another global administrator from your tenant, they can help you to reregister your MFA.

    Admin has to perform below steps to reset your MFA so that you can re-register for authenticator app.

    • Admin has to login to Azure portal and access Microsoft Entra ID.
    • Once done they have to go to user's blade on the left.
    • Click on the user account which is unable to login to Azure portal.
    • Click on Authentication methods and click on “Require re-register multifactor authentication”.
    • Now when you try to login to Azure, it will prompt you to register for MFA again.

    If you are not aware of another global administrator or you are the only global admin in your tenant, please let us know. We will guide you further.

    If the resolution was helpful, kindly take a moment to accept the answer and upvote it 👍 it as a token of appreciation.

    Thank you for helping to improve Microsoft Q&A!

    @Shubham Sharma Thanks for your help! I contacted the administration and revoked my multifactor authentication sessions, and got logged back in successfully.
