How To Add Twitter, Facebook and OpenID Support To WordPress

I’ve just added the RPX WordPress Plugin to this site that allows readers to sign-in without having to enter a password by using their OpenID, Google, Yahoo!, AOL, Windows Live, Facebook login details or MySpace ID.  Full features:

• Adds passwordless sign-in and commenting to your blog via OpenID, Google, Yahoo!, AOL, Windows Live, Facebook, and MySpace based authentication.
• Attach a third party sign-in provider to your existing WordPress account.
• Create new accounts without registering and maintaining a password.
• Easy to configure with no template modifications required.
• Verified identity and provider icons for blog commenters.

Installing the plugin was very easy.  All I had to do was:

1. Install the plugin
2. Get a RPX API Key – this was done within the WordPress dashboard
3. Choose what ID providers I wanted to support – six can be added for free
4. The Authentication icons are automatically added to the page
   

I’m very tempted to tick the option requiring all commenters to authenticate.  One of the original reasons I moved to WordPress from blogware was becuase blogware didn’t allow unregistered comments, and I thought it was unfair requiring all readers to register just to leave a comment (it was a full registration).  However, just about everyone has a twitter, facebook etc account so I think this will be an acceptable move, and might also reduce comment spam.

Do you think this will be a safe move?
