OpenID is an [open standard][] that allows users to authenticate to websites
without having to create a new password. This plugin allows users to login to
their local WordPress account using an OpenID, as well as enabling commenters
to leave authenticated comments with OpenID. The plugin also includes an OpenID
provider, enabling users to login to OpenID-enabled sites using their
own personal WordPress account. [XRDS-Simple][] is required for the OpenID
Provider and some features of the OpenID Consumer.
Developer documentation, which includes all of the public methods and hooks for
integrating with and extending the plugin, can be found [here][dev-doc].
