Joomla! has a limited access control system. By default there are the following groups:
Front End Only
  • Public
  • Registered
  • Author
  • Publisher
Back End
  • Manager
  • Administrator
  • Super Administrator
There are two basic ways that access controll is used:
  • To control the ability of users to see modules, content and menu items
  • To control the actions that users can take.
Access to content, modules and menu links

All groups except Public and Registered are considered "Special."

When creating content or setting parameters for modules, you can set access to: Public, Registered or Special.

These groups are hierarhical. Groups further down the list have all rights of those above them.

Control of privleges to create and edit content and modify administrative settings.

Each group can view the content and modules at the same level or above on this table.

There is no way to create additional access groups without modifying Joomla! core files.

There are some extensions available which provide additional access control capabilities.
