Simple, privacy-sensitive single sign-in: let your users sign in to your website with their email address, and free yourself from password management.

Mozilla Persona is a cross-browser login system for the Web, that's easy to use and easy to deploy. It works on all major browsers, and you can get started today. Why should you use Persona on your website? Persona completely eliminates site-specific passwords, freeing users and websites from the burden of creating, managing and storing passwords securely. Persona is easy to use. With just two clicks a Persona user can sign in to a new site like Voost, bypassing the friction associated with account creation. Persona is easy to implement. Developers can add Persona to a site within a single afternoon. 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. Plus, Persona is only going to get better: it's built on an open, decentralized protocol, that's designed to allow direct integration into browsers and native support by email providers. Sites that implement Persona today will automatically experience improvements without having to change any code.
