This document discusses OpenID, which is an open standard that allows users to log into multiple websites using a single digital identity. Some key points: - OpenID allows for simplified sign-ins by using an identity provider like AOL, Yahoo, or Google instead of creating multiple usernames and passwords. - Benefits include single sign-on access across sites, easy signup, and decentralization. However, there are also security, privacy, and usability challenges to consider. - The author implements OpenID on their own site using their MyOpenID or OpenID.net account, and encourages others to get an OpenID and try logging into enabled sites.

6. The Ugly Usability Issues Explanations (where they exist) aren’t simple/non-technical yet Without using the registration extension, requires profile duplication Privacy Issues Tracking Hacking Reuse/Recycling of user names could cause privacy breaches http://www.flickr.com/photos/28801512@N00/2491827977/
