WordPress.org

Does this plugin provide a full OpenID provider?

No, this plugin delegates to a third party provider. You can run your own provider using phpMyID or something similar, or you can use a full-service OpenID provider such as MyOpenID or one of these.

How do I get help if I have a problem?
