As part of the V2 experiment for Special:Create Account (T422295, which included the changes from the V1 experiment), we made a number of changes to the password field on that page.
This task is about upstreaming these changes into mediawiki core.
Acceptance criteria
- The GrowthExperiments extension no longer has code modifying the password fields on Special:CreateAccount or Special:UserLogin
- The adjustments that were made during the experiment to these fields for the treatment group are now available in MediaWiki core as the default experience.
- The following aspects should be verified as working as expected:
- Special:Create Account, Special:UserLogin
- visiting/using these pages as anonymous, temporary, or named user
- visiting/using these pages both on desktop (=Vector2022) and on mobile (=Minerva)
- when logged-in: checking the check-box that says "Use a temporary random password and send it to the specified email address"
