You can access cPanel using two different ways.
Through our website
Go to: https://webhs.pt and click on 'Login'
Enter your login details to access WebHS customer area.
On your costumer area click on "Services"..
.. and then click on the plan name to which you want to access cPanel.
Then, on your side menu, click on 'Enter cPanel'.
And that's it.
Through direct URL
If you have your domain / subdomain already pointed to WebHS servers, you can access cPanel using direct URL (you should change 'DOMAIN.COM' to your own domain):
https://cpanel.DOMAIN.COM (Service subdomain)
https://DOMAIN.COM:2083 (using cPanel secure port)
