Need Data Protection / Tenant Recovery team to reset MFA/Security

Answer 1

Hello Sahrudin Sudi Saeraji,

Thank you for sharing your details (user's email address, tenant id, phone number, country code and country) with us over Private Message

I have reached out to the engineering team to unblock MFA for your account. They have now unblocked it from the backend and removed the bad reputation on it. You should be able to log in to the Azure Portal without any issues.

Please try logging in and check if you can complete SMS authentication without any errors. Let me know if you encounter any issues.

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