37signals Product Blog: We’ll be retiring our support of OpenID on May 1. The support costs far outweighed the benefits to customers, especially now that 37signals have their own single sign in mechanism that works across all of their products. # 25th January 2011, 4:17 pm

Vox is closing on September 30, 2010. One month seems like very short notice for closing a service of this size, especially since it functions as an OpenID provider so in addition to migrating their content away users may need to sign in to other services and set up an alternative form of authentication. UPDATE: From the comments, Vox accounts that migrate to TypePad will also have their OpenID migrated, and TypePad will continue to serve OpenID requests for old vox.com addresses. Smart solution. # 3rd September 2010, 8:50 am

RasterWeb: Lanyrd. Pete Prodoehl calls me out on Lanyrd’s integration with the Twitter auth API at the expense of OpenID. I’ve posted a comment with my justification—essentially, tying to Twitter’s ecosystem means I can actually implement the features I’ve been talking about building on top of OpenID for years, with far less engineering effort. # 31st August 2010, 8:49 pm

App Engine at Google I/O 2010. OpenID and OAuth are now baked in to the AppEngine users API. They’re also demoing two very exciting new features—a mapper API for doing map/reduce style queries against the data store, and a Channel API for building comet applications. # 20th May 2010, 3:30 pm

Stack Overflow Blog: OpenID, One Year Later. Google’s support is a huge deal—61% of Stack Overflow accounts use Google. Google’s implementation of directed identity has caused problems though, since Google provide a different OpenID for each domain making it hard for Stack Overflow, Server Fault and Super User to correlate accounts. Their solution is to require a (verified) e-mail address from Google OpenID users using sreg and use that as a key for the accounts. # 14th April 2010, 8:46 pm

RFC5785: Defining Well-Known Uniform Resource Identifiers (via) Sounds like a very good idea to me: defining a common prefix of /.well-known/ for well-known URLs (common metadata like robots.txt) and establishing a registry for all such files. OAuth, OpenID and other decentralised identity systems can all benefit from this. # 11th April 2010, 7:32 pm

Yahoo! OpenID: Now with Attribute Exchange! The nice thing about this is that an e-mail address obtained from Yahoo! via attribute exchange has already been verified, so you don’t need to perform the e-mail roundtrip yourself. I expect a lot of OpenID consuming sites will end up with internal whitelists of OpenID providers who they trust to provide verified e-mail addresses, with users of sites not on the whitelist still getting e-mailed a verification link. # 5th December 2009, 5:25 pm

OpenID: Now more powerful and easier to use! The OpenID+OAuth hybrid protocol (where a user can sign in with OpenID and grant an application access to their OAuth protected resources such as a contact list at the same time) is now supported by Google, Yahoo! and MySpace—this feels like OpenID finally coming of age. # 25th September 2009, 9:08 pm

Evidence of OpenID at Amazon. It looks like Amazon are using OpenID for SSO between their different properties—I clicked a link to sign in to AWS and the URL had OpenID query string parameters. # 6th July 2009, 1:25 am

Exclusive: The Future of Facebook Usernames. I have to admit I was planning to just let Facebook get on with it, assuming that the OpenID provider part would show up of its own accord—but maybe I should write a thoughtful and persuasive essay about it after all. # 11th June 2009, 9:46 am

Sign in with Twitter. Intriguing: Twitter are now an OpenID-style identity provider... using OAuth. # 20th April 2009, 4:10 am

“Recover my account” link on the login page. For the record, collecting and verifying e-mail addresses is a VERY good idea, even (especially?) if you accept OpenID. A verified e-mail address is still absolutely the best way to deal with lost passwords or “my OpenID isn’t working”. # 16th February 2009, 10:22 pm

Plaxo sees 92% success rate with OpenID/OAuth hybrid method. Really wish I could have been at the OpenID UX Summit hosted by Facebook yesterday—sounds like an awful lot of important problems are being solved. # 11th February 2009, 5:20 pm

Want Proof OpenID Can Succeed? Just Scroll Down. “It’s easier for blogs, which don’t need a lot of demographic information about a user, to let people jump in and start participating socially without filling out a registration form.” Aargh. Repeat after me: supporting OpenID does not mean you can’t require additional registration details through a signup form. # 16th January 2009, 12:16 pm

Wetpaint no longer supports OpenID. I missed this, but they turned off their OpenID support in November due to low usage and high maintenance costs. # 8th January 2009, 2:53 pm

Talking about OpenID. “So a relying party walks in to a bar...” # 5th January 2009, 10:46 am

Getting OpenID Into the Browser. David Recordon makes the case for online identity management as a key browser feature (I like the “your browser is currently locked” concept), and argues that Gears is in a great position to deliver it. # 3rd December 2008, 10 am

Clearing up inaccuracies about the Google OpenID IDP launch. Google took some undeserved flack when they launched their OpenID provider. For the record, whitelisting providers fits my definition of the “Open” in OpenID perfectly (providers and consumers are free to impose whatever policies they like). # 8th November 2008, 11:11 pm

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

Windows Live Adds Support For OpenID. I hope they include the option to log in to the provider using CardSpace, to address phishing. # 27th October 2008, 9:34 pm

Yahoo! Releases OpenID Research. Extremely valuable research, conducted with a group of typical Yahoo! users. OpenIDs usability remains bad, and if we don’t get it right soon something centralised like Facebook Connect will take over and the Web will stop being open. # 14th October 2008, 4:59 pm

Google’s Usability Research on Federated Login. Fascinating—suggests an approach to federated auth based on the Amazon.com “Yes, I have a password” login flow. Feels convoluted to me but apparently it tests really well against a mainstream audience. The more research shared around this stuff the better. # 22nd September 2008, 8:56 pm

OSCON in 37 minutes. 45 OSCON talks summarised by their presenters in just 37 minutes, compiled by Gregg Pollack. I get to rant about OpenID for a minute at 27:22. # 29th July 2008, 11:59 pm

Email Address to URL Transformation (EAUT) specification now available! Allows OpenID users to login using their E-mail address, which is converted in to an OpenID URL based on rules specified in an XRDS document attached to the root domain. Seems like a good idea to me. # 22nd July 2008, 7:30 pm

MySpace To Join OpenID, Bringing Total Enabled Accounts to Over A Half Billion. Another 200 million OpenIDs—but the important difference between this and the Yahoo! and AOL announcements is that MySpace users know what their profile URL is. Whenever people have told me OpenID is flawed because people don’t understand URLs I’ve answered “sure they don’t, but they know their MySpace page”. # 21st July 2008, 7:42 pm

RefactorMyCode.com. Neat community for discussing improvements to code snippets. Login using OpenID. # 28th June 2008, 11:46 pm

OpenID phishing demo (via) A demonstration of the OpenID man-in-the-middle phishing attack. idproxy.net OpenIDs are immune to this particular variant due to the landing page not asking for your password (the phishing site could still provide their own redesigned landing page and hope users don’t notice though). # 28th May 2008, 8:09 am

Byteflow Blog Engine. This looks like the most full-featured of the Django blog engines by a pretty big margin, including OpenID client and server support. A product of the growing Russian/Ukrainian Django community. # 11th May 2008, 7:41 pm

SourceForge Allows OpenID Logins. Excellent—SourceForge is the kind of site that I log in to infrequently enough to always forget my password (and indeed username) making OpenID a great fit. # 1st May 2008, 1:05 pm

HTML 5 vs. Yadis. The draft HTML5 spec currently disallows values for http-equiv and link rel which aren’t listed in the spec—meaning both methods of specifying a link to an OpenID server are invalid for HTML5. This should probably be fixed... # 19th April 2008, 4:35 pm
