Wikipedia:Interface administrators

Interface administrators are users who are able to

  • Edit any user's custom CSS, JavaScript, and JSON pages
  • Edit the site-wide CSS, JavaScript, and JSON, whether for a specific skin or for everyone
  • Edit pages in the MediaWiki namespace, which affects the text in the wiki's user interface

This right is distributed by bureaucrats on an as-needed basis and removed when the needed edit is made.


Previously, all administrators could edit any CSS and JavaScript page on the wiki. However, in view of possible security concerns, this user group was introduced to all wikis and the above rights revoked from administrators[1] following a WMF-wide consultation. This change was made effective in late August 2018.


  1. Administrators continue to retain the right to edit JSON and other non-code pages in the MediaWiki namespace.
