This is a process controlling the authenticity of the users identity on the basis of the two following factors: Something You Know — for example, the user name and password. Something You Have – for example, the CD device.

Two-factor authentication (T-FA) is an authentication protocol that requires two forms of authentication to access a system. This contrasts with traditional password authentication, which requires that a user only know a password to gain access to a system.
