# User Management

User management in Connectware allows you to control access to your systems through well-defined identities and permissions. This chapter explains how to manage users, roles, and permissions.

{% hint style="info" %}
Managing users and roles requires admin role privileges or corresponding permissions.
{% endhint %}

## Users, Roles, and Permissions

The main concept of managing access in Connectware is done via users, roles, and permissions:

* **Users**: A known identity (person or software/hardware agent) with associated data permissions and/or administrative access. See [Users](/documentation/user-management/users.md).
* **Roles**: A group of permissions that can be assigned to multiple users. See [Roles](/documentation/user-management/roles.md).
* **Permissions**: Specific access rights to resources (via MQTT topics or HTTP endpoints). See [Permissions](/documentation/user-management/permissions.md).

## Hardware Devices

For hardware devices connecting to Connectware, we recommend using the [Client Registry](/documentation/client-registry.md). Instead of manually creating user accounts through the Admin UI, the Client Registry enables:

* **Self-registration**: Devices can self-register using either MQTT or REST API approaches.
* **Secure credential handling**: Eliminates risks associated with manual password sharing.
* **Certificate support**: Advanced registration with certificate signing requests (CSR) for enhanced security.
* **Controlled approval**: Administrator review of all registration requests before granting access.
* **Granular permission management**: Newly registered devices have no permissions by default, allowing precise control over device capabilities.
