# Adding users to system groups

To apply permissions to users, start by activating the **role system** and **adding users to system groups**.

> [!WARNING]
> **System groups are the predefined groups in TuCalendi**, so you cannot create or delete groups. In the system groups, you can only add or remove the users that belong to each group.

[Log in to TuCalendi](https://account.tucalendi.com/) with your username and password. **In the upper right corner, click on the three vertical dots** to open the menu.

In the menu, select **"Role system/permissions"**:

> [!WARNING]
> By default, the role system is **disabled**. If you want to use the role and permission system, you must **enable** it.

## Activate role and permissions system

In the **"Use the role/permission system"** field, turn on the option so that the role system starts working.

Once the role system is active, click on **"System groups"**:

The available **system groups** are displayed.

## Super admins

Users in this group have the **same privileges as the account owner**, except that they **cannot delete the account**.
