Mozilla Persona Remote Verification API

Persona is a Mozilla project that aims to facilitate consumer verification via public-key cryptography. This means no more passwords to access a website, just e-mail addresses. Users might find this 2 click system beneficial because they will use an e-mail that is not easily forgotten, contrary to a password. As stated in the website, developers can value a direct communication with the user, since they will store a preferred customer e-mail address on the site. The API is about remote verification. Resources consist of HTTP method, assertion parameters, return values and examples in Javascript, PHP and Java.
