Answer 1

Try these steps to resolve Microsoft Authenticator sign-in problems:

1. Make sure the Authenticator app can complete login
   • Open Microsoft Authenticator on the phone and ensure it is unlocked.
   • If seeing a message like “Authenticator did not complete login”, complete the sign-in inside Authenticator, Company Portal, or the primary Microsoft app on the device.
2. Check notifications and network
   • Ensure push notifications are enabled for Microsoft Authenticator in the phone’s Settings.
   • Confirm the phone has internet access; if needed, switch between Wi‑Fi and mobile data and try again.
3. Update the app
   • Install the latest version of Microsoft Authenticator from the app store. Outdated versions can cause the “Authentication did not complete” error.
4. Verify device settings
   • Make sure the device date and time are correct.
   • If on Android and using a work/school account, ensure Google Play Services and Google Play Store are installed and enabled, and that push notifications are allowed.
5. If still unable to sign in
   • If the issue is that the login keeps asking for Authenticator but it cannot be used (for example, new phone or lost device) and this is a work or school account, contact the organization’s IT admin and ask them to reset MFA / authentication methods.
   • If this is a business tenant and there is only one admin and that admin is locked out, contact Microsoft Support by phone and request the Data Protection team to help reset the admin’s MFA, as described in the referenced Q&A posts.
   • If the problem is forgotten password, use the official Reset your password flow: Reset your password.

If none of the above works and access is still blocked, contact Support or the IT admin for the account to investigate and reset the sign-in configuration.
