WHM( WebHost Manager) is a resellers control panel. It is what reseller customers use to manage all the hosting accounts in their reseller plan.
cPanel on the other hand, is the end user’s control panel. It is what the reseller’s customers use to manage their
individual hosting acounts.
If you are logged into WHM, you can look at a list of hosting accounts in the reseller plan. Click on the Account Information link. Then click on the List Accounts link.
Here you will see the list of accounts in this WHM’s reseller plan. Once again, each of these accounts will have their own individual cPanel, and we can login to their cPanel by clicking the corresponding link.
As you can see here, we’re now in the cPanel control panel for the newdomain.com hosting account. Resellers have the ability to login to their customer’s cPanel control panels without their username or password. This can be useful in helping customers how to use their cPanel.
After you close the cPanel page, you can now return to the home page of the WHM.
You now know the difference between cPanel and WHM:
cPanel– end user’s control panel
WHM – reseller’s control panel
