Dear MARLIANA GLADWINA ANAK ASSUN 

Thank you for contacting Microsoft Q&A Forum.  

Based on your description, it appears that your account is a school account, and you cannot sign in your account. We would like to suggest you the way to resolve this problem:    

• If you are the only Global Administrator and you are completely locked out of your tenant, you may need to contact us via our phone support service: Customer service phone numbers - Microsoft Support. The support agent will create a ticket for you and transfer it to the Data Protection team, who can help you regain access.  
• If you're a normal user or there are other Global admins present, please contact them to request a Multi-Factor Authentication (MFA) reset. They will be able to assist you in regaining access to your account. To help them proceed, kindly ask your IT administrator to follow the steps outlined in the following Microsoft Learn article: Manage authentication methods for Microsoft Entra multifactor authentication - Microsoft Entra ID | Microsoft Learn 

We understand this can be challenging, and we appreciate your patience.   I hope this helps clarify your situation and guides you toward regaining access to your accounts. Please feel free to ask if you have any other questions.

Hello,

Microsoft does not directly manage organization users. Instead, each organization's IT administrator is responsible for managing its users according to its internal protocols.

You should contact your organization's IT support team. They need to reset your MFA for you in order for this to work. Once the reset is completed, follow these steps:

1. Open your web browser and navigate to https://login.microsoftonline.com.
2. Sign in to your account.
3. You will be prompted to set up MFA again. Make sure to update your phone number during this process.

If your organization's IT administrator requires guidance, they can follow these steps:

1. Sign in to the Microsoft Admin Center at https://admin.microsoft.com using their credentials.
2. Navigate to Users > Active Users in the left-hand menu.
3. Select the relevant user.
4. On the user card that appears on the right, scroll to the bottom and click Manage multifactor authentication.
5. On the MFA settings page, locate the user's name, select it, and click Manage user settings on the right.
6. In the pop-up box, check the first box and click Save.

This process will reset MFA for the user, allowing them to set it up again.
