How do I add another Lookout administrator?

Log in to your Lookout admin console and navigate to System then Settings.
 
Here you should have the option to select Manage admins.
 
Select Add new admin at the top right corner of your admin console and enter the details of the person you want to add as an admin. 
 
This will instantly generate a welcome email and send them a request to log in to the console as an admin.
