Thoughts on “How to Enable Two Factor Authentication in Joomla 3.5

  • I enabled the plugin, enabled the two factor auth. in the users settings, scanned in the barcode, but the “secret key field” isn’t showing up in the backend and I can still login using only the admins username and password.

  • Google’s two step authenticator works great for my joomla sites. The problem is when  I buy a new android phone, I can’t find any easy instructions for how to switch to the app on my  new phone. Today, I had to disable two factor authentication by going into file manager and renaming the plug in folder. This is such a hassle. There must be an easier way to move to a  new phone.
