Hi @connectfourstudio4

Thank you for posting your question in the Microsoft Q&A forum.  

Regarding your issue, may I kindly ask if you have other admin with at least authentication administrator in your organization? If yes, you can ask them (Global admin) to either unblock your account or reset your multi-factor authentication (MFA) for you.   

They can follow these steps:  

1. Sign in to the entra.microsoft.com as at least Authentication Administrator role. 
2. Select User -> All user.   Select the user (your account) to act on and select Authentication methods. then select Require re-register of multi-factor authentication.   
   • Require re-register MFA:  This disables all previous authentication methods. You'll then be prompted to configure a new MFA authentication method the next time you try to sign in, so you can set up from the start and add a new authenticator app.   

For more details, please refer to: Manage user authentication methods for Microsoft Entra multifactor authentication.

Note: Once re-registration is triggered, all your existing MFA methods such as phone numbers, Authenticator app, or other verification options will be removed. You will need to set up new MFA methods during your next login. Please ensure you have access to a valid phone number or the Microsoft Authenticator app before attempting to sign in again.  

If you are u the only global admin (IT Admin) and locked out, you must contact Microsoft Support for help: Customer service phone numbers.

Please remember to provide them with your account details and explain the situation. Be ready to provide:      

• The company name used during subscription     
• Billing email address (even if it’s a personal Microsoft account)     
• Payment method details (last 4 digits of the card, billing address)     
• Any subscription ID or invoice numbers from billing email     

To make the process smoother, here’s an example of how to respond when speaking to the automated system (IVR):      

IVR: What kind of problem are you concerned about?      

You:  Authenticator.     

IVR: What kind of product do you use?      

You: Office 365 for business.      

IVR: Education or company account?      

You: For companies 

IVR: Are you an administrator?      

You: Yes.      

IVR: Do you have the other administrator in your organization?      

You: No.      

IVR: Do you need a... Service request?      

You: Yes    

These prompts help direct your call to the right support team more quickly, especially when dealing with account lockouts and authentication issues.     

If you still cannot reach to agent, there is still a workaround, you might consider registering for a new tenant by signing up for a trial subscription via this link Compare All Microsoft 365 Plans | Microsoft. This would allow you to create a new tenant following the provided prompts.     

Once set up, you can access the admin console of the new tenant by logging into admin center and follow the steps in this article Get support - Microsoft 365 admin and submit a support ticket requesting to speak with the Data Protection team on behalf of your previous tenant.     

Please remember to cancel the trial subscription once your issue is resolved to avoid any unintended charges.     

As forum moderators, we don’t have access to the detailed system needed to troubleshoot this effectively due to privacy and security constraints. To quickly resolve this and regain access, the most effective step is to contact Microsoft Support Team directly. Only they have the ability to help with your Authenticator issue.     

Hopefully it will help work with your issue and if you have any other questions or need further assistance, feel free to ask.
