# Permissions
Many actions in Sentri require specific permissions. These permissions are configured per user group and can be set to one of the following levels:

- NA (Not Available)
- RO (Read Only)
- RW (Read Write)

> [!INFO]
> The **superuser** account has RW access to all permissions by default. This behavior is intentional and cannot be changed.
## Viewing or modifying permissions
To view permissions, you need the `admin-access-control-permissions` RO permission.

To modify permissions, you need the `admin-access-control-permissions` RW permission.

Navigate to **Access control** > **Permissions** and click the **view** icon. You will see the permission set assigned to each user group.

If you want to view or modify all permissions for a specific user group, go to **Access control** > **User groups**, then click the **view icon** next to the user group you want to view or modify. This will display the full list of permissions configured on that group.
