People are doing more and more online. They use Flickr to upload and share their pictures, they blog using Blogger and Livejournal, and chat using AOL systems. In addition to doing more online, the more they do, the more passwords they (tend) to have to know. They also have to create a discrete user profile for each new environment. With OpenID, those hassles could be over!
What is OpenID
OpenID is an open source community project that is intended to act as a centralised user-space. It is describes as:
a lightweight method of identifying individuals that uses the same technology framework that is used to identify web sites … It 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.(Source)
In essence, users will be able to carry their profiles and data with them, regardless of the service or content providers that they turn to. the major upshot, for consumers, is that it should mitigate some difficulties and hassles related to online lock-in. At the same time, it means that the different communities and spaces a person participates in will have access to that centralised knowledge basin, from which increasingly complex and rigorous digital portfolios can be developed.
