Locked out of Microsoft 365 Admin Center — Authenticator app signed out, no backup MFA method

Yelaman 0

Hello,

I am the Global Administrator of our Microsoft Exchange (domain: oppo-aed.kz). Recently Microsoft enforced new security policies requiring MFA for Admin Center access.

My situation:

Microsoft Authenticator app was signed out of my account on my phone for unknown reasons (password was not changed)
I have no other MFA method configured
I know my admin password and have access to my admin email
When trying to sign in, only the Authenticator code option is shown
"Sign in another way" only shows Authenticator as well

What I have already tried:

Adding the account on another device — still asks for Authenticator code
Accessing security info at mysignins.microsoft.com — requires Authenticator code
Microsoft Support account recovery — asks for a registered tenant email but rejects my admin email

Question: How can I regain access to my Admin Center as a locked-out Global Administrator with no working MFA method and no other admin accounts in the tenant?

Any help is greatly appreciated.

Hi @Yelaman,

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

I’m very sorry to hear about your situation. Regarding that you’re unable to log in to your global admin account.

If you don't have any other admin account in this situation, the Microsoft Data Protection team has tools and processes in place to verify identity and regain access to administrator accounts.

Please note that forum moderators have no control over user accounts, especially when it comes to logging in to your account, resetting your password, changing your access, etc.

Therefore, If you are the only administrator in your organization, then you need to involve Microsoft data protection team. Please try to find the related hotline number to call the frontline let them raise a ticket for you: Customer service phone numbers - Microsoft Support

*(Important Note: Depending on your country or region, 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, this is an automated conversation: First, when you call the hotline, they will ask you what kind of problem you are struggling with.

Answer: Authenticator.

A: What products do you use?

B: Office 365 for business.

Verification: Education or company account?

B: For companies

A: Are you an administrator?

B: Yes.

A: Are there any other administrators in your organization?

B: No.

A: I need one.... Service request?

B: Yes

If your organization's Office 365 Business/Education subscription is from a partner or reseller, and the global administrator is unable to open a service request on your end, contact the reseller's support provider to help open a service request on behalf of you instead.

Thank you again for your time and understanding.

I really appreciate your patience, and I’m here to help. Looking forward to your response.
