User Groups and Permissions

With Joomla's User Groups, ACL Permissions and Viewing Access Levels, you can create a website that is both flexible and secure. Joomla allows you to decide exactly what users can see and what they are allowed to do.

This can be useful for membership websites, company intranets, online communities, or any website where different users need different levels of access. You can control who can create, edit, publish, delete, manage, or only view content. All of this is possible with Joomla's built-in ACL system, without needing extra extensions.

In this explanation, Peter Martin will show you how Joomla User Groups, Permissions, and Viewing Access Levels work together. You will learn how Joomla controls access on both the frontend and backend, how permissions are inherited through the user group structure, and what the difference is between permissions and viewing access.

After understanding these basics, you will see why Joomla's ACL system is known as one of the most powerful and flexible access control systems available in a content management system.
