A recent usability study conducted by Yahoo shows that users are still confused by OpenID—the single sign-on technology out to eliminate multiple usernames and passwords. Tech site Webmonkey reports:

The study observed nine female Yahoo users in their thirties who considered themselves of medium-to-high internet savvy. The participants were told they could log in with their Yahoo ID at a third-party site. In many cases, the users tried to log in using the site’s main login, rather than the OpenID login. Users don’t understand multiple ways to log in, at least not without some education.

Truth be told, while the OpenID concept is very exciting, adoption has been disappointing—and it’s most likely due to the usability problems surrounding it. Over a year ago, Lifehacker alum Wendy Boswell ran down the pros and cons of OpenID, and her review was pretty mixed. Tell us whether or not you’re using and loving OpenID in the comments.
