Change security info problem

Hello @Jawad ALghadban,

Based on your description, it appears that your current MFA method is no longer accessible. In this situation, the existing MFA security information may need to be reset or removed so that you can register a new verification method, such as SMS, email, or the Microsoft Authenticator app, and regain access to your account.

Could you please confirm that you are the end-user or the IT admin of your organization? 

If you're an end-user, please reach out to your IT administrator/Microsoft 365 administrator and ask them to reset your MFA settings using the Microsoft Entra Admin Center. If you haven’t yet reached out, here’s a helpful guide to locate your Microsoft 365 administrator: How do I find my Microsoft 365 admin? - Microsoft Support  

 Ask your administrator to follow these steps:    

• Go to Microsoft Entra Admin Center: https://entra.microsoft.com  
• Navigate to Entra ID > Users > All Users.  
• Select your user account.  
• Go to Authentication Methods.  
• Click "Require re-register multifactor authentication".  

This will reset your MFA settings. The next time you sign in, you’ll be prompted to set up the Authenticator app again using a QR code.  

If you're an IT admin, please check to see if there are other IT admins in your organization who can help you with the reset. 

If you are the only administrator in this tenant, you will need to contact the Microsoft Data Protection team, as they are the only group authorized and equipped with the necessary tools and verification procedures to confirm your identity and restore administrator access. 

Please try to find the related hotline number to call the frontline and let them raise a ticket for you: Customer service phone numbers - Microsoft Support 

Depending on your country or region:

For some countries, when calling the support number, although there are about 30 seconds opening as something "you can visit the link...." But you can ignore this opening and wait until the option, then "1" as a education/business email user, "1" again for technical help.   

For some countries, it will be an automated conversation like:    

• First, when you call the hotline, it asks what kind of problem you are worried about.   
• Answered: authenticator.   
• A: What kind of product are you using?   
• B: Microsoft 365 for education.   
• A confirmation: education or company account?   
• B: For education
• A: Are you an administrator?   
• B: Yes.   
• A: Do you have the other admin in your organization?   
• B: No.   
• A: You need one.... Service request?   
• B: Yes   

Note:

• You may need to call multiple times before you are connected to a live support representative and can successfully create a support request with a ticket number for tracking. 
• If your subscription is from a partner or reseller, contact the reseller's support provider to help open a service request on behalf of you instead.   

I’d like to clarify that I don't represent Microsoft, I do not have access to user sign-in logs, cannot reset MFA, revoke access, or contact Microsoft Support/Data Protection Team on your behalf. Please consider me an end user as well, providing guidance based on experience and documented processes.

If you encounter any difficulties in contacting the frontline support, please feel free to let me know. Thank you and I wish you a great day!
