[OpenID] Combining Google & Yahoo user experience research

[Luke Shepard]

Just wanted to chime in with a link to Niall Kennedy¹s research into
auto-detection of likely providers:
http://www.niallkennedy.com/blog/2008/02/browser-history-sniff.html#openid-e
xample

In his scenario, the browser does some scanning in JS to determine likely
candidates. This is a promising solution to the problem of ³which providers
does this user have² (although potentially creepy).

Also, if that is too creepy, some identity providers may provide a way to
auto-detect whether the user is an active user of the site. For instance,
the Facebook APIs allow you to check (via JS) whether the user is currently
logged-in (but without actually getting their identifier or any information
beyond that). OpenID currently allows the remote site to check if the user
is logged in AND has authorized the website (via checkid_immediate),
although perhaps it could be adapted to check for simple membership.
