Click on "Client Area" then click on "Services" "My Services" click on "view details" you can now access your cPanel or Webmail. Do not change this password unless you are sure that no scripts are set up on your hosting that require the password, if this is changed you will need to edit the fields manually within the hosting for any scripts installed like Joomla or Wordpress.

You can access the cPanel any time by adding /cpanel to your domain name. Example, www.mydomain.com/cpanel
