Two-factor authentication also known as 2FA or 2-Step Verification is an authentication method that requires two components, such as a pin/password + a token.

This is a security process in which the user journey is taken to two different authentication factors to verify themselves as part of a security process. This is an extra layer of security that does not only require the user to enter his details but also to verify the person via a unique code sent via SMS.

  • Something you know (your password)

  • Something you have (like your phone )
