I am the only admin for my company and I can't access my admin account?

If you are the only global admin on your account and cannot access it, you should contact the Azure Data Protection team for assistance. You can reach them at +1 866-807-5850. If you have another global admin in your organization, you can also ask them for help to regain access to your account.

Additionally, if you are locked out due to issues with the authenticator app, you may want to check if you have set up other options for security verification. If those options are available, you can select Other verification options to try to regain access.

If you need further help, consider finding the appropriate contact at Support for Business Products.

Dear @JT Builders Operations, 

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

I'm sorry to hear you're experiencing difficulties accessing your work account due to issues with the Microsoft Authenticator app. Please know that you're not alone, many users face similar challenges, and we're here to guide you through each step to help you regain access and get back to work as quickly as possible. 

Please follow the steps outlined below to proceed with account recovery and regain access. 

Option 1: Contact Microsoft Data Protection Support by Phone (Primary Method)   

To regain access to your admin account as you can't access the Admin Portal, you can try reaching out to our Global Customer Service phone to raise a request for resetting your authentication method here: Customer service phone numbers - Microsoft Support. During the call, request to speak to an agent, and share with them every detail related to your query and also mention that you are the only admin who lost access to your account. This should allow you to contact the appropriate team so you can solve this incident as soon as possible.  

Here are some tips and an example of a prompt to help you navigate the IVR more effectively:        

In some countries, it is an automated conversation like:  

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 confirmation: education or company account?        

You: For companies        

IVR: Are you an administrator?        

You: Yes.        

IVR: Do you have another administrator in your organization?        

You: No.        

You: Yes. I need to create a ticket. Please send me direct to the Data Protection Team.   

Option 2: Create a Temporary Account (Trial Tenant) to Submit a Support Ticket (Alternative Method)  

If you still cannot reach to a live agent, there is still a workaround, you might consider registering for a new tenant by signing up for a trial subscription via this link Microsoft 365 Business Plans and Pricing | Microsoft 365. This would allow you to create a new tenant following the prompts provided. Once set up, you can access the admin console of the new tenant and submit a support ticket requesting to speak with the Data Protection team on behalf of your previous tenant.        

Please note that forum moderators do not have access to user account settings and cannot assist with logging in, resetting passwords, or changing access rights. While we do not have access to internal systems or administrative tools required to resolve account-specific or backend-related issues but we’ll continue doing our best to support you within the scope of our responsibilities.       

I hope this helps you regain access to your account quickly. I'm glad to assist and truly hope the information provided has been useful. Please feel free to reach out anytime if you need further assistance.
