Since the dawn of the Internet, the universal cry of pain has been “why can’t I log in to all sites with one password?.” The goal of universal identify is one that makes so much sense,
but that has been difficult to achieve because it requires the cooperation of so many.
Both corporations and nonprofits have tried to have a go at this holy grail. From Microsoft’s Passport to the recent OpenID initiative. These approaches have seen moderate adoption so far, and when I consider why, what I get is – not enough value. When you want to sign up for a site, these authentication services simply save you the need to fill one field — the password.
