Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi @Michelle LaPean,
Welcome to Microsoft Q&A forum.
Thank you for reaching out and sharing your co‑worker’s issue. I understand that she is unable to sign in to her Microsoft 365 admin account because the system continuously asks for a verification code from the Authenticator app.
Her admin account currently has Multi‑Factor Authentication (MFA) enabled. Because of this, each time she attempts to sign in, Microsoft will always request a code from the Authenticator app - even if she selects “Try another method.” When the Authenticator app is the only MFA method registered, the system will not allow login using just a password.
At this point, she has two options to regain access:
1. Contact another IT Administrator to reset her MFA
Please check whether your organization has another Global Admin who can reset the MFA settings for her account. They can follow the steps in the Microsoft article Manage user authentication methods for Microsoft Entra multifactor authentication. This will help them assist her in resetting her MFA settings and restoring access to her admin account.
2. If she is the only Global Administrator
If she is the sole Global Admin for the tenant, she will need to complete the account recovery process using one of the methods below:
Option 1: Contact Microsoft Data Protection Support by Phone (Primary Method)
To regain access to her admin account as you can't access the Admin Portal, she can try reaching out to our Global Customer Service phone to raise a request for resetting her 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 her query and also mention that she is the only admin lost access to her account. This should allow hẻ to contact the appropriate team so she can solve this incident as soon as possible.
Here are some tips and an example of a prompt to help her 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.
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 she still cannot reach to a live agent, there is still a workaround, she 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 her to create a new tenant following the prompts provided. Once set up, she 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 her previous tenant.
Just to clarify, moderators do not have the ability to view or change user account information, so we cannot help with login issues, password resets, or modifying access rights. Even though we cannot access the internal tools required for account‑specific fixes, we are here to support you in every way we can within our scope.
_Please remember to cancel the trial subscription after your issue is resolved, as this will help you avoid any accidental billing. She 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 your co‑worker regain access to her 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.
