Enter the addon domain you would like to add in the "New Domain Name" field 3. cPanel will automatically generate a subdomain username and document root for you (It is usually best to keep these the way cPanel sets them unless you have special requirements) 4.

Check the box once you have copied the password to a safe place 7. Click the "Use Password" button 8. Click the "Add Domain" button to finish creating the addon domain
