+
+By default, whenever you create a fresh cluster, an admin user is created,
+with the username `admin` and a randomly generated password.
+This password is printed out following the successful creation of the cluster.
+
+{{< callout type="info" >}}
+The password is printed following the successful creation of the cluster.
+It is not stored anywhere on the cluster, and it is not possible to retrieve it
+later. Thus, if the password is not saved in the install output logs, you must recreate the cluster to gain access.
+{{< /callout >}}
+
+An admin user can create users, change user passwords, and delete users from
+the MKE system.
+
+## Create users
+
+1. Log in to the MKE Dashboard as an administrator.
+
+2. Navigate to **Access Control** --> **Users** to access the **user** page.

+3. Click the **Create User** button at the far right to access the **User Creation** page.
+
+4. Enter the pertinent information into the following fields:
+
+   * **username**
+   * **password**
+   * **confirm password**
+
+   {{< callout type="info" >}}
+   You can enter the name of the user into the **name** field, however this is
+   optional and the input is not in use in MKE.
