# The TuCalendi role and permissions system

When you have a [work team](https://www.tucalendi.com/en/s/work-teams/tucalendi-for-work-teams), **TuCalendi's roles and permissions system is a fundamental component** for managing **calendars**, **events** and **reservations**.

**Roles are groups of users** that share specific permissions. **Permissions are privileges** or actions that a user or group of users can perform. They regulate **access and management capabilities** on the platform, from simple **reading** to **full system administration**.

There are two types of groups, and in each group you add users with the corresponding permissions:

## System groups

**These are the predefined groups in TuCalendi**. You can't delete them, and you can't create new system groups. In system groups, you can only **add or remove users** who will be part of these groups.

The permissions of each system group are as follows:

- **Super admins:** Users in this group have the **same privileges as the account owner**, except that they **can't delete the TuCalendi account**.
- **Admins:** These users can **manage all TuCalendi functions or features**, except for the **account settings**.

> [!WARNING]
> A TuCalendi account can only have **one owner**, but it can have **multiple Super admins** and also **different Admins** for account management.

## Custom groups

**These are groups you can create, modify or delete**. In them, you can add or remove different team members and assign them the **corresponding permissions**.

Within custom groups there are two roles:

- **Group administrators:** These are users who can **manage the group**, creating **calendars or events for the group members**.
- **Users:** These are the work team members who don't need to manage anything on behalf of other users. They have **read permissions**, although you can also give them permission to **manage their own events**.

> [!WARNING]
> A **group administrator** can belong to **several custom groups**.
