What is an Authenticator app?

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 the 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.

Each website has its own guide on how to enable two-factor authentication. For more detailed instructions on how to enable 2FA for your favorite websites, you can visit our 2FA Guides.
