# ClickHouse® User Management

For each cluster, one administrator user is automatically created. The administrator username is admin. The administrator password is set when [creating a cluster](/managed-databases/clickhouse/create-cluster.mdx). Once the cluster is created, the password cannot be viewed in the Control Panel, but it can be [changed](#change-administrators-password).

The administrator user can manage other cluster users via SQL queries. Read more about user and role management in the [Access control and account management](https://clickhouse.com/docs/operations/access-rights) section of the ClickHouse® documentation.

## Change ClickHouse® Administrator Password \{#change-administrators-password}

1. In the [Control Panel](https://my.selectel.ru/vpc/default/dbaas/), on the top menu, click **Products** and select **Managed Databases**.

2. Open the **Active** tab.

3. Open the database cluster page → **Settings** tab.

4. In the **User password** block, click **Change**.

5. Enter a new password or click **Generate**. The password must contain:

   * at least 12 characters;
   * latin letters of different cases;
   * digits;
   * special characters — `!?@$%&*.`.

6. Copy and save the user password — it cannot be viewed in the Control Panel after saving.

7. Click **Save**.
