Protecting your users' data with just a username and password is no longer satisfactory. Two-factor authentication (2FA) is the primary method of countering the effects of stolen passwords, and it is easy to implement in your web application. In this session, we will discuss what two-factor authentication is, how it works, and the challenges associated with it. We will then look how to integrate two-factor authentication into your PHP application's login workflow. We'll consider a Google Authenticator implementation, so you can make your users' accounts more secure. Finally, we will cover some plugins that WordPress & Drupal developers can use to enable this easily!
