Azure MFA session revoke

Question

I have 3 tenants in Azure. I can log into 1 and 2 fine, but not 3.

For 3, the MFA was setup with my old phone that broke. Our admin team has revoked my access and sent me the invitation to join.

The invite directs me to the my apps page, with no option to setup MFA again. When I try and access the azure portal for tenant 3, it still sends an MFA request to my old phone.

Hello @Storm H,

Thank you for posting your query on Microsoft Q&A.

It seems that for tenant 3, you're unable to log in because the MFA prompt is being sent to your old phone, which you no longer have access to. Since you're unable to complete the MFA, and your admin team has revoked your access and sent you an invitation to rejoin, it appears that the previous MFA registration was not fully removed.

Please request your admin team to revoke and reset the MFA registration for your guest user account. They can follow these steps:

1. Sign in to the Microsoft Entra admin center as an Authentication Administrator.
2. Navigate to Identity > Users > All Users.
3. Select the user account in question and go to Authentication Methods.
4. At the top of the window, select the appropriate option to reset the MFA for the user.

Once this is done, you should be able to log in and complete your new MFA registration.

I hope this information is helpful. Please feel free to reach out if you have any further questions.
