Portier

Portier (pronounced "Por-tee-ay") is a self-hostable login service that you can use instead of passwords. Portier sits between your website and third-party services like Google Sign-In to provide your users the fastest and easiest login experience, without ever needing a new password.

Best of all, Portier works for everyone, because it can fall back to traditional "click the link" methods of email confirmation.

• Email-first: Email addresses are decentralized, self-hostable, and useful on their own, so Portier uses email addresses instead of usernames to identify users.

• Connected: Whenever possible, Portier integrates with major APIs like Google Sign-In to provide seamless, in-browser identity verification.

• Decentralized: Anyone can host their own Portier Broker; there are no centralized dependencies.

• Open and Transparent: Because Portier uses email addresses, there is never any lock-in.

Portier is inspired by many projects and considers itself a spiritual successor to Mozilla Persona.
