YubiKey two-factor authentication (2FA) integration

A two-factor authentication system authenticates the user based on two factors, something the user knows which normally is a combination of their user name and/or password and something the user has in their physical possession which in our case is the YubiKey. Two-factor authentication provides high security and is many times required for compliance with regulations. Two-factor authentication can also be called two step verification or multi-factor authentication.
