The Role of Multi-factor Authentication for Modern Day Security

Abstract

Multi-factor Authentication (MFA) often referred to as Two-factor Authentication (2FA), which is a subset of MFA, is the practice of implementing additional security methods on top of a standard username and password to help authenticate the identity of a user and increase the security of data.This chapter will investigate the problem with username and password logins, the different types of authentication, current best practice for multi-factor authentication and interpretations about how the technology will grow in the upcoming years.
