Hello @Jaz Sia,
Thank you for posting your query on Microsoft Q&A.
Based on your description, it appears that you are unable to log into the Azure Portal due to an incomplete MFA process. Since the device registered for second-factor authentication are not getting any MFA prompts, you are unable to complete the authentication.
In such scenarios, another Global Administrator can help to re-register MFA on a new mobile device. In this situation, you need to contact your IT team or your tenant Global administrator to reset your MFA registration.
Please share these steps with your IT team or admin team to reset your MFA.
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.
Then you can login back to any office application and register with new MFA auth method.
If you are the only Global Admin in the tenant, this qualifies as a tenant lockout scenario. To resolve this, we need to engage the Data Protection team via a support ticket to unblock your access.
To proceed, I will need a few details from you. As this information contains Personally Identifiable Information (PII), please share the following details via private message:
- Contact phone number
- Contact email address
- Global admin email address (affected account)
- Country
- TimeZone
Please send me the detail via private message.
We can then connect offline to discuss further and assist you in resolving this issue. I hope this information is helpful. Please feel free to reach out if you have any further questions.
