@ashley wrote on a patch set:

The code is fine and does what it says on the tin, but the extension has a much bigger problem: namely it's been broken since AuthManager was introduced and no-one's maintaining and/or fixing it, and as such it should probably be archived instead.

To-do list

• This task
  • Add maintainers of that extension as subscribers to this task (if they have no apparent Phabricator account, notify them on-wiki or via email if possible and note it here).
  • Add Phabricator project <#ProjectX> as a tag for this task, or MediaWiki-extensions-Other if there is no project. (Requested in T205293)
• On-wiki documentation
  • Archive documentation on mediawiki.org (https://www.mediawiki.org/wiki/Extension:EditAccount): replace page contents with {{Archived extension|3191112|EditUser|reason=Broken since AuthManager was introduced; see also [[phab:T221494]]}}.
  • If documentation page was translatable, remove <translate>, visit Special:PageTranslation, and click "remove from translation" (if you don't have the translation administrator right, ask a user who does).
  • Archive Wikidata item associated with documentation page (https://www.wikidata.org/wiki/Q21676224) (remove nearly all statements, except instance of (P31) = MediaWiki extension (Q6805426), which should add a qualifier end time (P582) = the YYYY-MM-DD date that you decided to archive extension, generally per edit history, change English (and other languages if possible) description to "archived MediaWiki extension" (and its translation)).
• Phabricator
  • Archive Phabricator project <#ProjectX> for the extension.
  • Mark all Phabricator tasks for the extension either Declined or Invalid.
  • Edit Phabricator project <#ProjectX> description for the extension with a link to this ticket.
• Translatewiki.net/translations
  • Remove from translatewiki.net (groups/MediaWiki/mediawiki-extensions.txt) (add translatewiki.net project as a tag for this task).
• Configuration/tests/integrations/etc.
  • Remove from mediawiki/extensions (along with in .gitmodules).
  • Remove tests in [[ https://gerrit.wikimedia.org/g/integration/config | integration/config ]] (zuul/layout.yaml).
  • Remove manifest/other references from mediawiki/vagrant if they exist.
  • Remove from https://doc.wikimedia.org/cover-extensions/ if present (requires Continuous-Integration-Infrastructure shell user to delete directly from the server).
• Repositories
  • Empty repository leaving only the README indicating the repo is archived and referring to this task by URL.
  • Mark the repository read-only in Gerrit (Edit description to prepend "[ARCHIVED]" and append Task reference): https://gerrit.wikimedia.org/r/#/admin/projects/mediawiki/extensions/EditAccount
  • Archive the diffusion repository for the extension: rEEDA
  • Delete the GitHub mirror: https://github.com/wikimedia/mediawiki-extensions-EditAccount
