WHM, short for Web Host Manager, is a program that allows administrative control of cPanel. It is commonly used by hosting resellers to control multiple cPanel accounts for their users. WHM access is only available on VPS hosting and dedicated servers. (You can find out more about different types of hosting offered by name.com.)
At this time, Name.com does NOT offer WHM access, as all our hosting is shared and comes with one cPanel login per account.
