SSH, the secure shell, is often used to access remote Linux systems. Because we often use it to connect with computers containing important data, adding another security layer is recommended. Here comes the two-factor authentication (2FA).
Multi-factor authentication is a method of confirming your identity using at least two different ways of authentication. The most common and easiest to implement example of two-factor authentication uses a combination of passphrase (a complex password, often made of several words) and one-time passcode generated by a special mobile app.
We will use the Google Authenticator app for Android (in the Play Store) and iOS (in iTunes) to generate authentication codes.
