User
Explanation
A user account holds a person's credentials, their profile information and their preferences, and the wiki stores each one as a Page carrying an XWiki.XWikiUsers object, rendered by the User Profile Application.
Administrators manage those accounts from the wiki Administration and from the profiles themselves. They add and delete users, edit an existing profile, enable or disable an account without deleting it, change any user's password, and set the password security policy that later password changes must satisfy. They also customize the registration Page new users sign up through, and handle the accounts that email verification leaves inactive. User Management documents each of these.
Administrators also decide what a profile shows: they can choose which information the User Profile tab displays for every user of the wiki. What those users may then do is governed by Rights, and who the wiki takes them to be by Authentication.
