Request for Assistance – Unable to Access Microsoft Developer Account with Microsoft Authenticator

Phan Duy Thanh 0

Dear Microsoft Support Team,

I am currently unable to log in to my Microsoft account because my phone is broken and I no longer have access to the Microsoft Authenticator app. When I try to sign in, the system asks for a verification code or approval from the Authenticator app, which I cannot provide.

I attempted to use SMS verification as an alternative, but unfortunately, SMS messages are not being delivered to my phone.

I would appreciate your guidance on how to recover access to my account, such as verifying through my backup email or phone number.

Thank you very much for your assistance.

Best regards

Update: My account is a developer account with administrative rights (******@xxx.onmicrosoft.com).

Based on the details you’ve shared, this appears to be a tenant lockout scenario.

To resolve this, the recommended approach is to contact the Microsoft Data Protection team. You can reach them by calling Microsoft Customer Service using the phone numbers listed here: https://support.microsoft.com/en-us/topic/customer-service-phone-numbers-c0389ade-5640-e588-8b0e-28de8afeb3f2

If you have access to another tenant or subscription where you still have Global Administrator privileges, you may also raise a support request from there to get assistance in restoring access to the affected tenant.

For future reference and to help prevent tenant lockouts, please check: https://learn.microsoft.com/en-us/partner-center/customers/gdap-preventing-tenant-lockouts

If neither option is possible, let us know, we are happy to assist you further!

Hi Phan Duy Thanh

If you are the only Global Administrator and you are completely locked out from the tenant. So, only Microsoft Support team can help you in this MFA issue. You might need to contact Microsoft 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.

To connect directly with a real person when you call Microsoft support, the call must include the term AdminCenter, and the role must be specified as Global Administrator.
In the description of the request, the term AdminCenter must also be mentioned.
During the telephone dialog, if asked about another administrator, you can answer “no.” The call will then be forwarded to a real support agent, and a service request can be created.

If you cannot reach a real person via a support call, you can try to use a Trial Business Account to Submit a Ticket via Admin Center. Please visit the Microsoft 365 Business Plans and Pricing | Microsoft 365 and click Try for free to set up a trial account.

More details on how to get help from Microsoft 365 support can be found here: Get support - Microsoft 365 admin | Microsoft Learn

Note: If you decide to use the trial account option, please make sure to cancel the subscription once your issue is resolved to avoid any unexpected charges.

“Here, there are three options but none of them work. Options 1 and 2 require logging in with Microsoft Authenticator, and the SMS option is not working.
