Manual:User rights

User rights are specific access and ability permissions that can be assigned to customizable groups. Groups can then be assigned to (or removed from) users through the Special:Userrights interface in the wiki software. See Help:Assigning permissions.

Access to this interface is itself governed by the 'userrights' right, so only users in the 'bureaucrat' group can do it (in a default set-up) See Manual:User rights management for information about managing and the assignment of user groups.

This Special:Userrights interface was introduced in MediaWiki 1.5; see Manual:User rights management for earlier methods.

A default MediaWiki installation assigns certain rights to default groups (see below). You can change the default rights by editing the in  with the syntax

If a member has multiple groups, they get the highest permission of any groups. All users, including anonymous users, are in the  group; all registered users are in the   group. In addition to the default groups, you can arbitrarily create new groups using the same array.

Examples

This example will disable editing of all pages, then re-enable for users with confirmed e-mail addresses only:

This example will create an arbitrary "ninja" group that can block users and delete pages, and whose edits are hidden by default in the recent changes log:
