An anonymous reader writes "Like most web users these days, I have enough accounts on enough websites – most of which have *inconsistent* password syntax restrictions — that when I need to log into a site I don't visit very often, I now basically just hit the "Forgot Password" button immediately. Microsoft's "Passport" gave us the promise of a single web sign-on. What happened to that idea? Why hasn't some bright spark (or ubiquitous web corporation) already made a fortune standardizing on one? I can now buy my coffee with my phone. Why do I have to still scratch my passwords on the underside of my desk?"
