WP OpenID Selector is the adaptation of openid-selector (http://code.google.com/p/openid-selector/) to wordpress.
Openid plugin (https://wordpress.org/extend/plugins/openid/) is needed to use wp-openid-selector.
Users who want’s to authenticate (register) on a wordpress blog with openid system, only need to click on the their logo’s provider, instead of writing it’s url, to be automaticaly redirected to their openid server and proceed to the authentication.
You can see the plugin in use on our web site (http://www.st2i.com) or on the stackoverflow web site.

WP OpenId Selector

Adaptation of OpenId Selector for wordpress

Benjamin Atkin

This plugin adds the required meta tags to delegate OpenID to a http://myopenid.com/ account.
<h3>Troubleshooting</h3>
If rewrite rules from a caching plugin, or custom rewrite rules, cause the page to do a 301 
redirect, login will fail, at least for some sites. Remove these rewrites to fix it.

MyOpenID Delegation

This plugin delegates OpenID to MyOpenID.
