# User Management

Access to the MAT application is regulated: only users who have been invited can access the application. Furthermore, each user can view a limited set of dashboards and pages and perform only certain operations, depending on the permissions granted to them within the application. In particular, these permissions are represented through group membership: belonging to a group means enjoying all the privileges that the group grants to its members.

Permissions within MAT are divided into:

* permissions for accessing sections;
* permissions for viewing assets.

A user must have asset viewing permissions to be able to see the machines, and section access permissions to navigate within the application and view various pages. For more information regarding permission management, please refer to the [dedicated section](https://40factory.gitbook.io/mat-webapp-1/2.15.3/cybersecurity/roles).

The User Management section allows you to manage everything related to users, access to the application, and permissions, in order to control what each person can view within the application.

The module is composed of the following sections:

<table data-view="cards"><thead><tr><th></th><th data-hidden data-card-target data-type="content-ref"></th><th data-hidden data-card-cover data-type="files"></th></tr></thead><tbody><tr><td>User Management</td><td><a href="user-management/user-management">user-management</a></td><td><a href="https://content.gitbook.com/content/jkCM7skZiW9DRfJyyrrE/blobs/kzSIvXOAiEG5VWx55aio/um_userManagement.png">um_userManagement.png</a></td></tr><tr><td>Profiles</td><td><a href="user-management/profiles">profiles</a></td><td><a href="https://content.gitbook.com/content/jkCM7skZiW9DRfJyyrrE/blobs/t7jhF1yGUfscJ5CBlNbp/um_profiles.png">um_profiles.png</a></td></tr><tr><td>Groups Management</td><td><a href="user-management/groups-management">groups-management</a></td><td><a href="https://content.gitbook.com/content/jkCM7skZiW9DRfJyyrrE/blobs/PiEWpBZQ6cCSlkoe2Hiu/um_groupsManagement_functionalGroups.png">um_groupsManagement_functionalGroups.png</a></td></tr></tbody></table>
