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.

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.
