Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
For a work account, there is no supported way to generate codes if the Authenticator registration for that account is broken or missing in the app. The supported recovery path is:
- On the sign-in screen, try a different verification method if one is available.
- Look for another MFA option already registered on the account.
- If repeated sign-in attempts were made, stop retrying. Microsoft Entra multifactor authentication can temporarily block additional attempts after unusual activity. Wait and then try again, or use a different MFA method.
- In Microsoft Authenticator, check the basics for the affected account.
- Make sure the app opens normally and the account is still listed.
- Update Microsoft Authenticator from the device app store.
- Restart the device.
- Make sure the app is unlocked, notifications are enabled, the device has internet access, and date/time settings are correct.
- If no alternate sign-in method works, contact the organization’s IT administrator or helpdesk.
- Ask them to reset the MFA methods for the work account so MFA can be registered again.
- If suspicious activity is possible, ask the IT administrator to review the Microsoft Entra sign-in logs.
- After access is restored, re-register Microsoft Authenticator for the work account and add another verification method as backup if the organization allows it.
If the issue is specifically a temporary Authenticator failure such as the app not responding correctly, Microsoft documents these steps in order: wait a moment and retry, confirm the app launches without errors and the account is listed, update the app, check Company Portal compliance on work/school devices, and restart the device. If that still fails, send logs from Authenticator using Send feedback and then reach out to the IT admin.
