 * I never activate the Two factor authentication code. Now I cannot login.
 * I receive an email with the code which lasts for 5 mins, but have no idea how
   to use it.
 * Very embarrassing.

 * Every seemed ok, but never ever saw a box to enter the code. I had to ask the
   hosting company to rename the plugin, so I could login and then reinstalled the
   Plugin, and deactivate the 2FA.
 * Did a new scan and see these files
