You may have heard of OpenID before, or possibly even used it without ever realizing it. Below, I'll actually explain to you what OpenID is and give you a few reasons on its importance on the internet today.
Until OpenID was created in 2005, there was one huge problem with the web that still continues today. For each website you signup for, you have to re-enter all of your personal information, re-enter an email address, create or reuse the same password, hope you can get the same username you always use and set up your profile all over again. In the age of increasing social sites like Facebook and portals like AOL.com, this can get tiresome, tedious, and be a putoff to join something new. That's the basis for what OpenID is.
As the website explains, OpenID "eliminates the need for multiple usernames across different websites, simplifying your online experience". What typically happens first is the selection of an OpenID provider, like Verisign Labs, Google, or even AOL Instant Messenger. Each provider may add something different to the mix, such as AOL, in which all instant messenger service usernames are also OpenIDs. Next, if you come across a website that you would like to register for that supports openid, you will select the option to use it OR click on a link that says "sign in with you _____ username". In this case, let's use myspace for example. The next screen typically will ask you for a credential URL and an email address, so in this example, it would be myspace.com/username. You will then be forwarded to your OpenID profile page to be asked if you will allow the new service access to your information, and confirm that with your username and password. Finally, you will be asked to transfer over some information, such as your first and last name, birthdate, email address, and other items.
Not only does this allow you to keep a digital profile that you can use anywhere, it also helps you to keep your information safe. It is also a free, standards-based service, so you don't have to worry about it not being supported in the future (unless, your OpenID provider happens to go out of service, but most providers are really big an established companies). Also, related to a topic we will discuss in the future called "data portability", this sets up the possibility of taking your entire profile with you in the future. Not just your personal information, but information with friends you already have, being able to comment without re-requesting people to save you to their lists, and further simplifying your socyial online experience.
