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.
