Joomla! maintains two primary classifications of user groups. The classifications are primarily Front-end and Back-end user groups. Front-end users are only allowed to log in using the public facing side of the website. Back-end users are allowed to log in on the administrative side of the web site. As a result these users are also referred to as administrative users, or admins.
Administrative logins are available by default at
The most privileged of these users belong to the Super Administrator group. Super Administrators have the highest privilege level and can make changes or add new features or content to any section of a Joomla! site.
