The page on meta seems to propose some level of federated authentication with a 3rd party service along with sweeping adoption of this federated identity service by Wikimedia wikis. Actual implementation would likely require creation of one or more MediaWiki extensions (possibly with TechCom-RFC approval), many on-wiki RfCs for approval by various communities, and possibly WikiMedia Foundation Board level approval for deeper contractual interactions between Wikimedia and the 3rd party service.

From a WikiJournal User Group point of view, these would also be very interesting (technical wishlist). I'm pretty unfamiliar with Phabricator. What'd the best way to restart this? Especially:

1. Request new users to a wiki to suppy an ORCID iD
2. Provide a facility for a user to include their ORCID iD in their Wikimedia profile, through their preferences page
3. Allow users to register for an ORCID through the signup page/ their preferences page
4. Allow users to verify their ORCID and associate it with their Wikimedia identity
5. Allow users to sign in to ORCID with their Wikimedia logon (probably the most difficult)

Not quite. It suggests a range of possible scenarios, listed "in ascending order of estimated complexity and time-taken".
