WordPress utilizes an idea of Parts, intended to give the site proprietor the capacity to control what clients can and can't do inside the site. A site proprietor can deal with the client access to such undertakings as composing and altering posts, making Pages, characterizing joins, making classifications, directing remarks, overseeing modules, overseeing subjects, and overseeing different clients, by relegating a particular part to each of the clients.

WordPress has six pre-characterized parts: Super Admin, Administrator, Editor, Author, Contributor and Subscriber. Every part is permitted to play out an arrangement of errands called Abilities. There are numerous abilities including "publish_posts", "moderate_comments", and "edit_users". A default set of abilities is pre-allocated to every part, except different capabilites can be relegated or evacuated utilizing the add_cap() and remove_cap() capacities. New parts can be presented or evacuated utilizing the add_role() and remove_role() capacities.

The Super Administrator part permits a client to play out all conceivable capacities. Each of alternate parts has a diminishing number of permitted capacities. Case in point, the Endorser part has recently the "read" ability. One specific part ought not be thought to be higher ranking than another part. Or maybe, consider that parts characterize the client's duties inside the site.
