In WHM, different websites are stored in user accounts. It's possible to view a complete listing of all the accounts managed by WHM and to access the corresponding cPanel accounts. You can do so by opening the "List Accounts" menu in the "Account Information" section.
Start by searching for "List Accounts" in the search box to the top left. Simply click on the link that appears.
In this list, you can open the domain or website associated with each account, as well as open the cPanel page by clicking on the cPanel icon.
