OpenID and Facebook authentication support for blog comments

This blog now allows readers to post comments if they authenticate via OpenID.

As described earlier, I tried the OpenID plugin for WordPress, but that plugin required a PHP extension not supported by my web hosting provider.

I subsequently found the WordPress RPX plugin that supports OpenID. RPX is an outsourced authentication service run by a company called JanRain. The WordPress RPX plugin calls the RPX servers, which in turn do the OpenID handshaking with one’s OpenID provider.

Conveniently, RPX also supports authentication via one’s Facebook login. In all cases, the user’s password is sent only to the identity provider (Yahoo, Google, Facebook, etc) and is never shared with the RPX servers or my own site.
