Being tech-savvy, smart and (statistically speaking) a good looking reader of this site, you will have no doubt heard of Open ID. Open ID was created to allow you to have just one ID which can beused on multiple websites meaning that you don’t need to remember lots of different user names and passwords. In the words of the site:
OpenID eliminates the need for multiple usernames across different websites, simplifying your online experience.
You get to choose the OpenID Provider that best meets your needs and most importantly that you trust. At the same time, your OpenID can stay with you, no matter which Provider you move to. And best of all, the OpenID technology is not proprietary and is completely free.
For businesses, this means a lower cost of password and account management, while drawing new web traffic. OpenID lowers user frustration by letting users have control of their login.
For geeks, OpenID is an open, decentralized, free framework for user-centric digital identity. OpenID takes advantage of already existing internet technology (URI, HTTP, SSL, Diffie-Hellman) and realizes that people are already creating identities for themselves whether it be at their blog, photostream, profile page, etc. With OpenID you can easily transform one of these existing URIs into an account which can be used at sites which support OpenID logins.
OpenID is still in the adoption phase and is becoming more and more popular, as large organizations like AOL, Microsoft, Sun, Novell, etc. begin to accept and provide OpenIDs. Today it is estimated that there are over 160-million OpenID enabled URIs with nearly ten-thousand sites supporting OpenID logins.
Open ID >> What is Open ID?.
So how does a single sign on affect us here and now? Well, if you browse down to the comments section (bottom of the page), just as you go to put in a witty, insightful comment you’ll see a small addition to the “website” field:
Put your Open ID into it (for example, <user ID>.pip.verisignlabs.com) and submit your comment. If you don’t have one and really want one, go to the information page How Do I Get One? and sign up with a provider of your choice. To make life even easier, once you have an Open ID and if you go via Verisign, get the Verisign Seatbelt Firefox Plugin which will autosign you in to the relevant enabled websites.
