Imagine never having to remember another username and password again.
That's the promise of OpenID, which aims to eliminate "the need for multiple usernames across different websites, simplifying your online experience." Instead of signing on to a website with a username and password, you can sign onto OpenID-capable sites using a URL (like yourname.myopenid.com).
You may be surprised that you already have an OpenID. Yup. If you have an account with Yahoo, Flickr, AOL, or one of many other sites, you already have one. Microsoft and Google made news this week by announcing support for OpenID.
On the next Spark, we'll take a look at OpenID and how it can be used to manage your online identity. We'll also look at some of the security concerns, such as phishing (thanks Ryan) that crop up around this kind of federated login system.
What do you think? Do you have more usernames and passwords than you can remember? How do you manage them? Leave your comments below, or call them in to 1-877-34-SPARK.
