Multi-Factor Authentication (MFA) is a security system which uses 2 or more authentication factor to allow access to the user rather than just one Pin, Password or authentication factor to allow access. The very basic and main advantage of this system

Multi-factor authentication systems indicate that more than one factor must be used to prove the identity of an online user. A typical second element is an SMS code that is sent to a registered handy number of the user (often referred to as a one-time password). This widely-spread method, however, has proved to be vulnerable, critically.
