Dear @Vazira,
Thank you for posting your question in the Microsoft Q&A forum.
Based on your description, I understand how urgent this situation must feel, especially you have an exam this Sunday. Please know you’re not alone in this, and I’ll guide you through every step to get you back in control as quickly as possible.
Since you are using an education account, and your school has an MFA setting for your account, I highly recommend you contact your school IT staff directly so that they may reset your MFA settings. You might also ask whether your MFA can be temporarily disabled to allow an emergency sign-in.
For that reason, only your school IT admins have permission to revoke MFA sessions and require re-registration in Microsoft Entra admin center
For more information and instruction, please ask the school IT Admin to follow the Microsoft Official Guide here: Manage authentication methods for Microsoft Entra multifactor authentication - Microsoft Entra ID | Microsoft Learn
If you do not know who your IT admin is, please follow the information in the Microsoft Document here: Find the administrator for your work or school account
Note: Please understand that as forum moderator, my primary goal is to provide helpful guidance and support through general troubleshooting steps. While I don’t have access to internal systems or test devices required to resolve backend/account issues, I truly appreciate your understanding of these limitations. I genuinely hope the information I share helps guide you in the right direction, and I'm always here to assist as much as I can within my scope.
I hope this information is helpful. Please follow these steps and let me know if it works for you. If not, we can work together to resolve this. If I misunderstand anything, please feel free to reach out.
I'm looking forward for your reply.
