Website authentications are not regulated on the Internet which means that every website or service practically uses their own authentication that only uses on their site but not on other sites on the Internet.
OpenID tries to change that by giving users one ID that they can use to sign up for many different websites and services. Many major websites and companies already supported OpenID including Google, Facebook, Yahoo, MySpace, Wordpress and AOL.
It basically means that users who have, say a Gmail account, can use the information from that account to sign up for Facebook. This works either by connecting the two services (sign in to your Google Account to create a Facebook login) or by using a specific user name (for instance your Google profile URL) to sign up for another service.
The main benefits of OpenID are an accelerated sign up process, greater control over the online identity and better security.
You'll find bloggers talking about OpenID at sites like those run by Don Martelli and Ben Werdmuller.
