New OpenID Implementations Abound. I’ve missed linking to a bunch of OpenID news recently—in particular, Google Accounts are becoming OpenID identifiers and LiveJournal has quietly ugraded its consumer support to OpenID 2.0. # 30th October 2008, 5:11 pm

Yahoo!’s provider implementation only supports consumers that talk the Auth 2.0 protocol. Technically the 2.0 spec allows providers to shun 1.1, but it’s not recommended for the reason that I’m sure will become obvious once Yahoo! launches: there’s no way for your average end-user to distinguish between a 1.1 and a 2.0 implementation.

Relying Party Best Practices. Proposed guidelines for OpenID consumers from Martin Atkins, currently under discussion on the mailing list. # 7th March 2007, 11:45 pm

Despite it being a best practice, currently only a handful of OpenID Consumer sites support the association of multiple OpenID identifiers to a single “account”. This is important to create redundancy to make the loss of an identifier less catastrophic.

More on Decentralised Social Networking. Martin Atkins has been thinking hard about the practicalities of building decentralised social networking on top of OpenID. # 26th February 2007, 10:15 am

Group Membership Protocol. Martin Atkins’ proposal for a simple “is OpenID X a member of group Y?” protocol, useful for whitelists that can scale to handle large numbers of entries. # 22nd January 2007, 8:27 am

OpenID users can be just as trusty as local users. Martin Atkins makes a similar argument to my own: OpenIDs are trustworthy, provided you subject them to the same authentication steps (CAPTCHA/e-mail validation) as regular users. # 16th January 2007, 11:13 am
