"Persona" vs. "BrowserID"

Persona is a complete implementation of a new, distributed login system from Mozilla.

BrowserID is the open protocol that governs how Persona works.

Common Persona Terminology

BrowserID
An open, decentralized protocol for authenticating users based on email addresses.
Identity Provider ("IdP")
Services which issue credentials to their users.
Email providers can become Identity Providers for their users by adding support for the BrowserID authentication protocol to their service. If an email provider doesn't support Persona, Mozilla operates a fallback Identity Provider at login.persona.org.
login.persona.org
A fallback Identity Provider run by the Identity team at Mozilla.
Persona
The user-facing name of a complete suite of identity-related services from Mozilla, including the Mozilla-operated fallback Identity Provider. End-users should never see the term "BrowserID."
Persona may eventually include features beyond the BrowserID protocol, such as parts of Firefox Sync or a dashboard for Open Web Apps.
Relying Party ("RP")
Any website, application, or service that allows users to log in via Persona.
