OpenID is a new way to identify yourself all over the web. With your own personal OpenID you can login to any OpenID-enabled site (there are over 1,000 of them and that number is growing everyday) and identify yourself as you.
This is a short by-example talk about OpenID, what it does and can provide for your website. The talk includes a sample implementation in perl.
