Activating and using an OpenID is quite easy — I was able to sign up for TravelWiki, for instance, using one from Yahoo!. Activation and setup took about a minute. I’ve embedded three videos below that explain more about how OpenID works and how to use it. Enjoy!
The video below explains more about how to use an OpenID to login, in this case to votay.com:

And finally, in a Google TechTalk, Simon Willison (co-creator of the Django Web framework) discusses the implications of OpenID and explores the best practices required to take advantage of the new technology while avoiding the potential security pitfalls. This one’s a bit long but excellent.
