Have an OpenID account? Sadly, you're in a minority. But what you probably have is an abundance of usernames and passwords scattered all over the web. I use Roboform2Go to manage them. My Mac friends swear by 1Password. An effective solution for authentication without new registrations has been to use social applications like Facebook (Facebook Connect) and Twitter (OAuth) to authenticate. But those systems are still based on being part of a larger ecosystem. Mozilla has introduced a new browser-based form of authentication using your e-mail address called BrowserID. As the Web becomes more personalized, users need inter personalization with services, but on their own terms, explains Ragavan Srinivasan of Mozilla. The advantages of BrowserID and similar authentication schemes is that developers don't need to actually code authentication or sharing tools. It makes development easier and faster, and hopefully more secure for the user.
