Hi,
Thank you for reaching out to the Microsoft Q&A Forum.
I appreciate you posting your question, and I’m sorry to hear that you’re unable to access your work account due to issues with the Microsoft Authenticator app.
Because this is a work (organizational) account, all settings related to password resets, MFA (multi‑factor authentication), and authentication method recovery are fully managed by your organization’s IT administrator. When your company enforces MFA, they determine which verification methods are available such as the Microsoft Authenticator app, SMS, phone call, or email and they also control whether additional methods can be added or reset on your account.
Your IT admin will need to assist you by resetting your MFA or updating your authentication methods so you can regain access.
You can reach out to your IT administrator and share the steps outlined in the article Manage user authentication methods for Microsoft Entra multifactor authentication. This will help them assist you in resetting your MFA settings, reset your password and restoring access to your account.
Once this is done, you’ll be prompted to set up MFA again during your next sign-in.
You can follow this guide to set up your MFA: Set up your Microsoft 365 sign-in for multi-factor authentication - 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.
If you have any updates, feel free to leave a comment under this post. I’ll be happy to assist further.
Thank you for your cooperation and understanding in resolving this matter
