In recent years, the development in Information technology has unleashed new challenges and opportunities for new authentication systems and protocols. Authentication ensures that a user is who they claim to be. The trust of authenticity increases exponentially when more factors are involved in the verification process. When security infrastructure makes use of two or more distinct and different category of authentication mechanisms to increase the protection for valid authentication, It is referred to as Strong Authentication or Multifactor Authentication. Multifactor authentication uses combinations of “Something you know,” “Something you have,” “Something you are” and “Somewhere you are”/“Someone you know”, to provide stronger remote authentication than traditional, unreliable single-factor username and password authentication. In this paper we do a survey on the different aspects of multifactor authentication, its need, its techniques and its impact.
