Access to IT servers and applications was usually control by username and password (what you know). However, passwords are increasingly easy to compromise as they can often be stolen or hacked. With two-factor authentication, it adds a second layer of security (what you have, like your phone or other mobile device) when you access to secured resources. It is a more secure method of verifying or validating your identity. In HKUST, we employ an application named Duo.
