Locked out due to lost 2fa

Question

I have a Microsoft 365 account that was managed by GoDaddy. I migrated it out to self managed, but it now has a m2fa attached which only allows Microsoft authenticator methods, or SMS.

The phone number attached to it ends in 2 numbers which are not mine and I cannot login to the authenticator as 2fa is enabled.

How can I remove that 2fa and replace with mine?

This is fairly urgent as I need to pay for the new account before the existing subscription runs out.

Hi James

If another Global Administrator exists, ask them to reset your MFA authentication methods and require re-registration. After that, you can sign in and register your own phone number and Microsoft Authenticator app.

If you are the only administrator, there is no self-service method to bypass MFA or remove the existing authentication methods. In that case, you will need to contact Microsoft Support and explain. Microsoft Support can create a support case and, after ownership verification, may involve the Data Protection team to assist with account recovery and MFA reset procedures.

You might need to contact them via phone service number: Customer service phone numbers - Microsoft Support. The agent will be able to create a ticket for you under the affected tenant and then transfer this ticket to Data Protection team who could help you to regain access.  

When a call is made to support, the first step is to provide an automated voice response from AI. Be careful, you won't be able to speak to a support representative if you don't respond appropriately here. 

Here's an example of a response that actually led to a support representative. Please refer to it. 

Q. Can you tell me if you are calling as a home user who uses a product or service at home or a business user who uses it in your business to provide the best assistance? 
A.I am a business user. 
Q. Thank you. Can you give me the details of your inquiry? 
A. Login technical support. 
Q. First of all, can you tell me which products you are inquiring about today? 
A. Microsoft 365 business Standard。 
Q. Please wait a moment, I understand Microsoft 365. Are you calling about a new case or an existing one? 
A. New. 
Q. To receive phone support, your phone number must be associated with your Microsoft 365 admin profile. To do this, go to aka.ms/m365profile. Again, it aka.ms/m365profile . This can take 48 hours. In the meantime, you can go to aka.ms/m365profile and file a case online. If you prefer, you can also text the link to the phone number you are calling. What do you think? 
A. The phone number is already linked to the link. 
Q. Can you tell me about the products in your inquiry? 
A. Microsoft 365 Business Standard. 
Q. Are you a Global Administrator? 
A. That's right. 
Q. I'm sorry. I didn't understand. Are you a global administrator for your domain? 
A. Yes, I am a global administrator for the domain. 
Q. If you have any inquiries, you can contact a Microsoft representative. Are you sure? 
A. Yes. Please. 
Q. Yes, I understand. Please wait a moment.

Please note that this team is always overwhelmed, so you might need to wait for them to call you, this should take 3-10 working days.

In case the phone line is not supportive, you can consider directly submitting a support request as a helpful workaround:    

-Create a temporary Microsoft 365 tenant using a trial license: Go to Microsoft 365 Business Plans and Pricing and click Try for free to set up a temporary Microsoft 365 tenant with a trial license.    

-Use this new account to sign in to the Microsoft 365 Admin Center and submit a support request on behalf of your primary (locked) account.   

-Click Help & Support    

Note: This method doesn't require you to use your new account for your business. Instead, it allows you to create a temporary global administrator account so you can submit a support request, as your original global administrator account is locked out due to issues with multi-factor authentication. The trial account is free for one month. Be sure to delete it after submitting your support request to avoid any automatic renewals or charges from Microsoft.     

For further instructions, you can follow this guide: Get support - Microsoft 365 admin | Microsoft Learn.   

I appreciate your understanding and patience in this matter. While I truly want to assist you, this issue is beyond the scope of my role as a forum moderator. I do not have access to internal databases or the ability to escalate cases directly to Microsoft’s internal teams. Therefore, please kindly contact the Microsoft Support team for the most efficient help.

Hi Hani-Ng,

Thank you for the comprehensive answer.

I will need to create a temporary account to raise a ticket.

This is my dad's account that he setup through GoDaddy and he is the only admin. They left thier 2fa on the account when migrating it over to self managed.

Thanks,
