To ensure the highest level of security for self-service password reset when only one method is required for reset, a verification code is the only option available to users. In these cases users should manually navigate to the Microsoft Authenticator app (or relevant companion app like Outlook), refresh by either pulling down or hitting the refresh button, and approve the request. In some rare instances where the relevant Google or Apple service responsible for push notifications is down, users may not receive their push notifications. Users view the notification, and if it's legitimate, select Verify. The Authenticator app can help prevent unauthorized access to accounts and stop fraudulent transactions by pushing a notification to your smartphone or tablet.

To get started with passwordless sign-in, see Enable passwordless sign-in with the Microsoft Authenticator. This authentication method provides a high level of security, and removes the need for the user to provide a password at sign-in. When the correct number is selected, the sign-in process is complete. Instead of seeing a prompt for a password after entering a username, a user that has enabled phone sign-in from the Authenticator app sees a message to enter a number in their app. Instead, users can register their mobile app at or as part of the combined security info registration at. Users don't have the option to register their mobile app when they enable SSPR.
