Authentication forms an important step in any security system to allow access to resources that are to be restricted. In this paper, we compare the advantages and disadvantages of two authentication methods. We begin with the details of existing systems in use and then compare the two systems viz: Two Factor Authentication (2FA), Risk-Based Two Factor Authentication (RB-2FA). We also introduce a new variation of the risk based two factor authentication system called the artificial-intelligence assisted two-factor authentication.

Risk- based authentication, Two- factor authentication.
