cPanel is a web hosting account management tool. It is available on all Linux hosting plans, including Shared Hosting, Reseller Hosting, VPS and Linux Dedicated Servers.
You only get one username per cPanel. If you create addon, parked and subdomains, those domains can be accessed by logging in to your main cPanel; you will not have a separate cPanel or separate login credentials.
The username and password to log into cPanel can be found in your welcome email. If you do not have the correct login credentials, please contact support.
