In addition to being accessible by the root admin, WHM is also accessible to users with reseller privileges. Reseller users of cPanel have a fewer features than the root user, generally limited by the server administrator. The features are generally limited to those which they determine will effect their customers’ accounts rather than effect the server as a whole.
