Sole Global Admin Locked Out of Microsoft admin centre due to Lost Microsoft Authenticator Phone

Question

Hello,

I am the sole Global Administrator for my organization's Microsoft 365 / Entra ID tenant. I recently lost the mobile device that hosted my Microsoft Authenticator app, and I am completely locked out of my admin account.

Details of the Issue:

• Account Type: Work/School (Global Administrator)
• The Problem: The login screen asks for the Microsoft Authenticator code, which I cannot provide.
• Attempted Fixes: I tried adding the account to a new phone, but it registers as a blank "Entra ID" token without generating verification codes because it was not scanned via a fresh QR setup code.
• Other Admins: There are no other Global Administrators or users with admin privileges in this tenant to reset my MFA.
• Break-glass Accounts: There are no emergency access or break-glass accounts configured.

I need to be routed to the Microsoft Data Protection Team to verify my identity (via DNS TXT record or billing details) and have my MFA methods reset. Could a moderator please escalate this, or advise on the fastest way to get a ticket opened with the Data Protection Team given that the automated phone system is difficult to navigate?

Thank you.

Hello @Ing. Anthony Quansah,

I'm sorry to hear that your only Global Administrator account is locked out.

I understand that navigating the automated phone system can be challenging. To help, I'd like to share the prompt that has successfully helped many other users reach the Data Protection Team and create a support request:

1. Find the related hotline number for your country to call the frontline and let them raise a ticket for you: Customer service phone numbers - Microsoft Support 

2. 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 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: Office 365 for business.   
• A confirmation: education or company account?   
• B: For companies   
• 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   

Important 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 organization's subscription is from a partner or reseller, contact the reseller's support provider to help open a service request on behalf of you instead.   
• If calling the support line in your region is difficult, you may try another regional support number that offers service in your language, or contact the English support line if you’re comfortable speaking English.

If you still have trouble using the frontline support, you can try set up a new trial tenant and submit your support request:    

• Visit the Microsoft 365 Enterprise Plans page: Go to Compare Office 365 Enterprise Pricing and Plans | Microsoft 365.    
• Choose a plan and start a free trial: Select any of the available plans and click "Try for free" to begin the trial setup process.     

• Follow the guided setup: Complete the steps to create a new Microsoft account and a new tenant. This will be a separate and independent Microsoft 365 environment.    
• Access the Microsoft 365 Admin Center: Once the new tenant is created, navigate to https://admin.microsoft.com/.    
• Go to Support:   
  • Click on "Help & Support" button like this image. 
  
  • Toggle Support Assistant option to OFF > Type your issue under "How can we help?" Box > click Get Help. 
  • The Contact Support button will become available, you can click on it now. 
  
  • Choose contact method: "Phone" or "Email"      
  
• Raise a support ticket: Describe your issue in detail. Crucially, you must clearly state that you are locked out of a different, pre-existing Microsoft 365 tenant where you are the administrator. Provide the following information about your locked account:      
  • The domain name of your locked tenant     
  • Your administrator account. 
  • Any error messages you are receiving.    
  • Details about the authentication issues you are experiencing.    
  • Your proof of ownership. 
  
• Finally, clicking on "Contact me".   

Important notes:

• This new trial tenant will not give you access to any of the data or settings in your original locked tenant. It is solely a temporary means to contact Microsoft support.  
• Be prepared for Microsoft support to ask for verification of your identity and administrative rights for the locked tenant.    
• The resolution time might be longer as you are contacting support from a different tenant.    
• Remember to cancel the trial subscription for the new tenant once your issue with the original account is resolved to avoid any unintended charges. You can typically do this within the Microsoft 365 Admin Center under "Billing" -> "Your products."  

I’d like to clarify that as a forum moderator, 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.  

That said, I’m happy to support you throughout the process. Once you’ve created the support request and received a ticket number, feel free to share it with me via private message. I can help you track the case and suggest next steps if needed. 

To access the private message, please refresh this page, you should see a pop-up at the top of your thread. Click on View message to review it. 

I hope you'll be able to reach the Data Protection team this way. If you still have any issue, please don't hesitate to reply. Wishing you a successful day!
