Log in to the Tenant Manager. Navigate to the Administration > User Management menu.  

The Users management page appears as shown below. The users listed here are “tenant managers” and will have access to the Tenant Manager UI, but not to any tenants. After logging in, the user info in the top header will display “Tenant Manager.” 

Select Actions > Add a menu option to create a new user. A pop-up window appears for configuration. You must enter the username, full name, email, password, culture, and time zone. Click the Create button to confirm.

 A new "tenant manager" user is added to the list, and a confirmation message appears in the top-right corner. 

You can select multiple rows to perform functions such as removing them, activating or deactivating users, setting the default culture, and configuring the default timezone.
