    Two-factor Authentication (2FA) or Multi-Factor Authentication is the ability to use at least two forms of authentication for a login. This adds an extra layer of security to your accounts for very little effort applied. This post will cover some of the methods available for client-side 2FA, as well as the pros and cons of each method.
