DESCRIPTION
A few people like to say that passwords are dead, but the reality is far from it. First of all, we can't get rid of passwords entirely, because the alternatives all suck: physical tokens are easy to lose and retina scans are pretty creepy. What we should focus on is eliminating site-specific passwords. Mozilla Persona was introduced at OSDC last year, but a number of new things have been added to it since. But more importantly, it's still the best shot we have at a decentralized web-wide identity system that works for average users and doesn't violate their privacy. So I'm back to show you what's new and to talk about what organizations can gain from adding native support on their domain. It's time to solve the password problem on the web.

decentralisation is the answer, but it's not
a product adoption strategy
we can't wait for all browsersto adopt Persona

solution: a temporaryjavascript shim
goal: trusted coderunning in the browser

localStorage.setItem("key", serializedKey);
var serializedKey = localStorage.getItem("key");
storage tied tologin.persona.org
