Recently, Mozilla launched Persona - a new sign-in system for the web that resembles OpenID but is even simpler (Please don't confuse it with their other initiative of the same name). The initiative will allow you to use only an email address to login - no password necessary. There's more info on how it all works (and how it differs from OpenID) and how you can implement it if you so choose. You can even try it out if you'd like to see it in action.

I'm not sure this will be the thing that replaces our standard login procedures but somethings gotta happen. The standard email / password paradigm is rife with insecurities - maybe this will be better. Or maybe it will be a flash in the pan in comparison to "Login with Facebook"? Either way, I'm glad to see it exists!
