Joomla! has a limited access control system. By default there are the following groups: Front End Only
- Super Administrator
There are two basic ways that access control 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 hierarchical. Groups further down the list have all the rights of those above them.
Control of privileges to create and edit content and modify administrative settings.
|Group||Front End||Back End|
|Public||Can view public pages||None|
|Registered|| Same permissions as "Public" |
Can view content and modules limited to registered. Can submit weblinks
|Author|| Same permissions as "Registered" |
Can submit but not publish content. Can edit his own content once published.
|Editor|| Same permissions as "Author" |
Edit any content.
|Publisher|| Same permissions as "Editor" |
Can publish and edit any content.
|Manager||Same permissions as as "Publisher"||Limited|
|Administrator||Same permissions as "Publisher"||Most privileges|
|Super Administrator||Same permissions as "Publisher"||All privileges|
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!'s core files.
There are some extensions available which provide additional access control capabilities.
