Hi @Danny Gaviria

Based on your query, I understand you have an issue with MFA authenticator app.

I believe there might be an issue with Authenticator app while sending the notification. Could you please reach out to your global admin or IT help desk and request for re registration of MFA. Here are the steps to be performed by Global administrator or authentication administrator: Also consider adding other authentication methods as phone call as well to avoid any authentication issues.

1. Sign in to the Microsoft Entra admin center as at least an Authentication Administrator.
2. Browse to Entra ID > Users.
3. Choose the user you wish to perform an action on and select Authentication methods. At the top of the window, then choose one of the following options for the user:
   • Reset password resets the user's password and assigns a temporary password that must be changed on the next sign-in.
   • Require re-register MFA deactivates the user's hardware OATH tokens and deletes the following authentication methods from this user: phone numbers, Microsoft Authenticator apps and software OATH tokens. If needed, the user is requested to set up a new MFA authentication method the next time they sign in.
   • Revoke MFA sessions clears the user's remembered MFA sessions and requires them to perform MFA the next time it's required by the policy on the device.

I hope this information is helpful. Please feel free to reach out if you have any further questions.
