Microsoft Authenticator is a mobile application designed to enhance online security. It provides multi-factor authentication (MFA), passwordless login options, and password autofill capabilities for various online accounts, including personal, work, and school accounts.
When MFA is enabled, after entering your password, you'll be prompted to verify your identity. This can be done by approving a notification sent to the app or by entering a time-based one-time password (OTP) generated by the app. These OTP codes refresh every 30 seconds and do not require a network connection.
