# Managing Users

Creating, editing, locking, and removing GridGain Control Center users, and exporting cluster session history.

There are two types of users in Control Center:

* Admin users - can manage users (lock/unlock accounts, grant admin privileges, etc.), as well as [update the Control Center license](/docs/tools/enterprise/control-center/admin-guide/license.md#uploading-license-via-ui)
* Regular (non-admin) users - can log in and monitor clusters

The person who activates a Control Center installation automatically becomes an admin user.

The admin users have access to the **User Management** tab of the **Admin** screen, where they can create and manage users.

To display this tab, click **Admin** on the left-hand-side navigation bar.

## View user list

The **User management** tab displays a list of the existing Control Center users. It includes the following columns:

| Column        | Description                                                      |

| Email         | The user's email.                                                |
| Company       | The user's company name.                                         |
| Country       | The user's country.                                              |

You can filter the user list using the **Filters** section to the right of the list.

## Export Session History

You can export the cluster session history to a `cluster-statistic-report-<from_date_to_date>.csv` file that includes the following columns: "clusterId, start, end". This file shows the cluster connection history for a specific period, where each "session" is the period between connection and disconnection.

To export session history:

1. Click **Export session history** on the tab toolbar.

   The **Session history** dialog opens.
