Introducing Yahoo! OpenID for Movable TypePosted: June 2, 2008
Today I am happy to announce the availability of the first Movable Type plugin to make use of [Movable Type 4.2](http://www.movabletype.org/2008/05/welcome_movable_type_42.html)’s built in support for [OpenID 2.0](http://openid.net/specs/openid-authentication-2_0.html). The [Yahoo! OpenID plugin for Movable Type](http://www.majordojo.com/projects/yahoo-openid.php) allows users to provide Yahoo! users with a specially crafted login experience specific to them:
Movable Type’s ability to allow developers to build these customized logins, such as the one for [AOL/AIM](http://notes.1ec5.org/archives/2007/08/25/aimopenid.html) and [WordPress](http://www.majordojo.com/projects/wordpress-openid-plugin-for-movable-type.php), helps to make OpenID accessible to everyone – especially [those who don’t understand that a URL can be used to login](http://www.majordojo.com/2007/02/what-openid-needs.php) to a web site.
[Movable Type](http://www.movabletype.org/) and [Drupal](http://drupal.org/node/152893) are the only blogging platforms that have support for OpenID 2.0 built into its core that I know of.
