 Hi, I'm Francois from the Mozilla Persona team. I love the web, but I think we have a problem. That problem is identifying users that come to our website. Now it used to be that we could just ask them to set a password and then we would be done. Unfortunately that solution does not scale, and it's becoming a real problem both for users and developers. Now what can we do about it? You may be thinking, why don't we just get rid of passwords entirely? Why would it be good? Well, what are we going to replace them with? Are we going to use fingerprint readers, iris scanners, hardware dongles? The reality is that this is hard because passwords are really convenient. So what can we do about it? Well one thing we could do is reduce the numbers, and that's exactly what we're doing with Mozilla Persona. We're trying to reduce the number of passwords that you need down to one, the one that you already use for your email. So my talk is about how we're doing that with Persona in a way that's secure and privacy respecting. So I will show you how the system is designed, and what our approach is for bootstrapping this decentralized protocol. Now don't worry, you won't have to join our social network just to log into other websites. See you at JSFOOL.
