Mozilla Persona is a completely decentralized and secure authentication system for the web based on the open BrowserID protocol. To ensure that Persona works everywhere and for everyone, Mozilla currently operates a small suite of optional, centralized services related to Persona.
Why should you and your site use Persona?
Persona completely eliminates site-specific passwords, freeing users and websites from the burden of creating, managing, and securely storing passwords.
Persona is easy to use. With just two clicks a Persona user can sign into a new site like Voost or The Times Crossword, bypassing the friction associated with account creation.
Persona is easy to implement. Developers can add Persona to a site in a single afternoon.
Best of all, there's no lock-in. Developers get a verified email address for all of their users, and users can use any email address with Persona.
Persona is built on the BrowserID protocol. Once popular browser vendors implement BrowserID, they will no longer need to rely on Mozilla to log in.

To get Persona going, we're hosting three services at https://login.persona.org: a fallback Identity Provider, a portable implementation of the navigator.id APIs, and an identity assertion verification service.
