I am a regular user of WHM & cPanel. Recently I found a bug in cPanel Release Build 20683 which is now running in three of our servers.
You login to WHM. Then Click List Accounts. Your hosted domains will be listed. You should noticed that there is an quick password and email changer from some recent builds. To change password and/or contact address of any domain, there is + following by the domain name. Now you click on the + icon for a domain. You will see the password of that domain is shown in the contact address box.
