As your issue description is primarily written in English, I will provide my response in English for your convenience. Please feel free to let me know if you would prefer the information in another language. 

Hi @Luboš Daniel,

Good day, and I appreciate the clear explanation of your concern.  

You mentioned that you are the only Global Administrator in the tenant and are currently locked out of your admin account, with self‑service password reset not configured and no access to MFA verification methods.

As part of the community support team, my access is limited and I cannot make changes to administrator-level settings. For security reasons, only Microsoft’s specialized support team has the necessary tools and permissions to assist with account-level issues such as MFA resets or advanced troubleshooting.

Since you are the sole Global Administrator for the tenant, please follow the steps below to complete the account recovery process 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 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:  

(When you call the support number, you may hear an introduction of about 30 seconds such as "you can visit the link...". You can ignore this introduction and wait until you are presented with the options. Then press "1" as a business email user, and again "1" for technical help.)        

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. 

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

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.   

Please remember to cancel the trial subscription after your issue is resolved, as this will help you avoid any accidental billing. You may prefer the following resource for detailed instructions: Cancel your Microsoft business subscription in the Microsoft 365 admin center | Microsoft Learn

I hope this helps you regain access to your account quickly. Please try the steps and let me know whether they resolve the issue. If the problem persists, we can work together to find a solution.
