OpenID is an <a href="http://openid.net/" rel="nofollow ugc">open standard</a> 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. <a href="https://wordpress.org/plugins/xrds-simple/" rel="ugc">XRDS-Simple</a> 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 <a href="http://wiki.diso-project.org/wordpress-openid-api" rel="nofollow ugc">here</a>.

Extremely easy to use. Just install and enter your email address. Users will immediately be able to log in with just a few clicks using Facebook Connect through Lil’Omi.
Users who login with Lil’Omi can customize a cool 2D avatar for themselves and select a username which becomes their default WordPress username and avatar on your site with a simple authentication step using Facebook Connect.
Lil’Omi makes user sign up simple. If a user has already signed in with Lil’Omi on one WordPress site, they are automatically signed into any other WordPress or Buddypress site that also uses the plugin.
Changes that this plugin makes to your site:
<ul>
<li>Lets your users have a unique, customizable avatar with millions of possible combinations.</li>
<li>Adds a “Login with Lil’Omi” button to your log in, registration, and comment forms visible to logged-out users.</li>
<li>Allows users to sign in via Facebook without sharing their personal name or photo with your site.</li>
<li>Makes new user registration much easier for users.</li>
<li>Increases the amount of users that sign up for your site by automatically signing in users that have already used Lil’Omi on other sites.</li>
</ul>
