<p><strong><a href="http://blog.stackoverflow.com/2010/04/openid-one-year-later/">Stack Overflow Blog: OpenID, One Year Later</a></strong></p> 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. <p>Tags: <a href="https://simonwillison.net/tags/directedidentity">directedidentity</a>, <a href="https://simonwillison.net/tags/email">email</a>, <a href="https://simonwillison.net/tags/google">google</a>, <a href="https://simonwillison.net/tags/login">login</a>, <a href="https://simonwillison.net/tags/openid">openid</a>, <a href="https://simonwillison.net/tags/registration">registration</a>, <a href="https://simonwillison.net/tags/sreg">sreg</a>, <a href="https://simonwillison.net/tags/stackoverflow">stackoverflow</a></p>

<p><strong><a href="https://sites.google.com/site/oauthgoog/UXFedLogin">Google&#x27;s Usability Research on Federated Login</a></strong></p> 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. <p>Tags: <a href="https://simonwillison.net/tags/amazon">amazon</a>, <a href="https://simonwillison.net/tags/authentication">authentication</a>, <a href="https://simonwillison.net/tags/federated">federated</a>, <a href="https://simonwillison.net/tags/google">google</a>, <a href="https://simonwillison.net/tags/login">login</a>, <a href="https://simonwillison.net/tags/openid">openid</a>, <a href="https://simonwillison.net/tags/usability">usability</a></p>
