Question

I am completely lockout of the tenant with the domain xxx.onmicrosoft.com. Cannot log in using authenticator app or phone number.

I have been called three times by the Microsoft team, and it has been analyzed by the Microsoft team, and they promised that the engineering team would call me back to recover my account, but it has been 2 days since I have heard anything. This problem has been going on for more than a week and is really disrupting work in our office because everyone cannot access Microsoft services, please help us as soon as possible so that our work can return to normal or maybe can you help me to recover it via registered SMS/phone?

This is the ticket that I have submitted to Microsoft, please respond as soon as possible. thank you

Hello Dedi Nurdiyansyah

Thank you for sharing your details via private message.

I’ve reached out to the engineering team regarding the MFA issue on your account. They have now unblocked it from the backend and cleared the bad reputation associated with it. You should be able to log in to the Azure Portal without any issues.

Please try signing in and verify if you can complete SMS authentication successfully. Let me know if you encounter any problems.

As a best practice, I recommend registering the Microsoft Authenticator method for your account instead of relying on SMS. SMS and voice call authentication methods are more vulnerable to IRSF attacks (telephony fraud) and are generally less secure.

For better practice, I recommend registering with Microsoft Authenticator method to your account instead of SMS method as these SMS/Voice telecom auth methods are susceptible to IRSF attacks telephony fraud.
