Authenticator is an app that generates secure two-factor authentication (2FA) codes for your accounts. When you set up your account with two-factor authentication (2FA), you will receive a secret key to enter into the Authenticator, usually, the key is in a QR code form.
This establishes a secure connection between Authenticator and your account. Once this secure connection is established, the Authenticator will generate a 6-8 digit code that is required to access your account. Even, if someone knows your password they still need the 2FA code to access your account.
Two-factor authentication (2FA), sometimes referred to as two-step verification, is an extra layer of security for your account in which users provide two different authentication factors to verify themselves. This process is done to better protect both the user's credentials and the resources the user can access.
Two-factor authentication provides a higher level of security than authentication methods that depend on single-factor authentication (SFA), in which the user provides only one factor - typically, a password or passcode. Two-factor authentication methods rely on a user providing a password, as well as a second factor, usually either a security code or a biometric factor, such as a fingerprint or facial scan.
