Setting Up a Remote Access Key
From Lunarpages Web Hosting Wiki
This is how you would setup a remote access key in Web Host Manager (WHM).
The first thing you would need to do is login to WHM. From the front page, click on "Cluster/Remote Access". Next, click on "Setup Remote Access Key".
If you are incorporating an external script that automates account creation and management, it will ask you for a remote access key. WHM automatically creates the encrypted code for you. Simply generate the key, copy and paste into your script. To generate the new key, hit the button marked "Generate New Key" button.
After doing so, you will be able to setup a remote access key in WHM.
