Two-factor authentication (2FA) is a method of requiring more than one credential to prove your identity. It adds an extra layer of security to your system by requiring users to provide more than one piece of information to authenticate successfully to an account or Linux host. The additional information may be a one-time password (OTP) sent to your cell phone via SMS or credentials from an app like Google Authenticator, Twilio Authy, or FreeOTP .
