What is Microsoft Authenticator?

Microsoft Authenticator, created by Microsoft, is a multifactor authentication app that offers an extra level of security for users' online accounts.

Microsoft Authenticator generates unique, time-based one-time passcodes that users must enter along with their regular credentials during the login process. These passcodes help verify the identity of the user, enhancing security by making it more difficult for unauthorized users to gain access to accounts, even if they have obtained the user's password.

In addition to one-time passcode generation, Microsoft Authenticator also supports push notifications for certain accounts, allowing users to approve or deny login attempts directly from their mobile devices.

Microsoft Authenticator is available as a mobile app for both Android and iOS devices, making it convenient for users to access their authentication codes and approve login attempts wherever they are. It's commonly used to secure various Microsoft accounts, including Outlook.com, Office 365, and Azure, as well as third-party accounts that support authentication through the app.
