How to fix the MFA authentication reset when we reset our mobile?

I recently reset my mobile phone and cannot access my learning portal account because the MFA authentication for my Microsoft account was removed from my mobile device. However, whenever I try to log in from another device, it asks for MFA authentication.

Hello Ashfaq Aasim,

Please check with any of the Global admins in your tenant to revoke your current MFA sessions and again re-register for MFA for your user account by following the below steps:

To manage user settings, please 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 "Revoke multifactor authentication sessions" and then select “Require re-register multifactor authentication” option for the affected user.

Please refer to the below Screenshot for your reference.

Please login to portal.azure.com and complete the MFA registration process and let me know the behavior.

Hello Ashfaq Aasim,

The issue pertains to a tenant lockout scenario, where there are no other global admins in your affected tenant to revoke MFA sessions and re-register MFA for your affected user account.

To resolve this issue, we have engaged our Data Protection team through a support ticket. They will reach out to you via email or phone to help restore access to the tenant and assist you in resolving this issue.

I have provided the details regarding the support ticket over the Private Message.

Once the issue has been resolved by our support team, please feel free to revisit and kindly click "Accept Answer," as this will be helpful to other community members facing similar issues.
