Computer Security: Multi-factor Authentication

This is the third post in a multi-part series on computer security essentials. I am not a computer security expert but there’s some basic computer security essentials that a surprising number of people don’t understand. The aim of this series is to raise awareness of these. I will be covering password vaults, two factor authentication, devices and local encryption.

Multi-factor authentication is a method of accessing your accounts whereby you need multiple factors of authentication: typically a combination of something you know (such as a password), something you hold (such as a device or card) and/or something about you (such as fingerprints or iris etc.).
