Project:Interface administrators

Interface administrators can edit CSS/JS pages that they do not own (that is, any page ending with  or   that is either in the   namespace or is another user's user subpage). In particular, they have the ability to edit sitewide CSS/JS pages (pages such as MediaWiki:Common.js or MediaWiki:Vector.css, or the gadget pages listed on gadgets>Special:Gadgets|Special:Gadgets). These pages are executed by the browser of wiki editors and readers as code, which can be used to change how content is styled, change the behavior of pages, or even create highly complex tools. In addition, they can also edit all other pages in the MediaWiki namespace.

The 1>Special:MyLanguage/Manual:User rights|right   was introduced into MediaWiki in Version .

Editing CSS/JS that gets executed in other users' browsers is very powerful and potentially dangerous in the hands of a malicious user. Interface administrators should be users who need it, who are trusted by the community, and who follow common basic password and computer security practices (use strong passwords, do not reuse passwords, use two-factor authentication, do not install software of questionable origin on your machine, use antivirus software if that's a standard thing in your environment).

Users can be added to this group by stewards>m:Special:MyLanguage/Stewards|stewards or bureaucrats>Special:MyLanguage/Project:bureaucrats|bureaucrats.
