Hi @Southern Acme Contractors,
Thank you for posting your question in the Microsoft Q&A forum, and I’m sorry to hear you're having trouble accessing your work account due to Microsoft Authenticator app.
This situation typically occurs when your account is protected by multifactor authentication and your registered device or number is no longer available, so approvals continue to route to a method you cannot use. Microsoft Authenticator push approvals are delivered by the Microsoft Authenticator app on the enrolled device rather than the Outlook app. During sign in, the system follows your configured methods in order, so if Microsoft Authenticator push is set as the default and that device is unavailable, you will need an alternate method or an administrator reset before you can update your phone number.
Regarding your situation, please kindly follow these steps to help regain access to your account.
Option 1: Contact your IT's admin
- First, reach out to your IT administrator to update your phone number on your account and reset your multifactor authentication methods so you can reregister from scratch.
- If you're an admin, please check to see if there are other IT admins in your organization who can help you with the reset MFA for your account and you can share the steps outlined in the article Manage authentication methods for Microsoft Entra multifactor authentication. This will help them assist you in resetting your MFA settings and restoring access to your account.
Option 2: Contact Microsoft Data Protection Support by Phone (Primary Method)
If you're the only admin, in this situation, the Microsoft Data Protection Team has tools and processes in place to verify identity and regain access to administrator accounts. 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.
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.
