This presentation is about the enabling and configuration of two factor authentication within the Joomla CMS. It starts with some theoretical background on why you need two factor authentication (2FA) and then focuses on the enabling of the Google Authenticator and Yubikey plugins in Joomla for enabling and configuring the 2FA. It also shows how to set it up on a per user basis on the front end as well as on the back end of your site.
This presentation is the English translation of the presentation I've done for JUG Vlaanderen at 15 Nov 2014 (original presentation in Dutch also available).
