Contao User Management: Roles and Permissions

Manage user roles, permissions, and team access in Contao — step-by-step admin guide.

This section covers user management, roles, and permissions for Contao and associated analytics tools.

Overview

Contao is a powerful open-source CMS originally developed in Germany, featuring an advanced user and permission management system. The platform distinguishes between two types of users: backend users (administrators and editors who manage content) and frontend users (website visitors with authenticated access). This dual-user system provides flexibility for both content management and membership-based websites.

Contao's permission system is highly granular, allowing administrators to control access to specific modules, content elements, page trees, and even individual database fields. Understanding this sophisticated access control system is essential for maintaining security and efficiency in your Contao installation.
