Please take the SSO Community Survey to let us know how we're doing, and to help us plan our roadmap!

sso — lovingly known as the S.S. Octopus or octoboi — is the authentication and authorization system BuzzFeed developed to provide a secure, single sign-on experience for access to the many internal web apps used by our employees.

It depends on Google as its authoritative OAuth2 provider, and authenticates users against a specific email domain. Further authorization based on Google Group membership can be required on a per-upstream basis.

The main idea behind sso is a "double OAuth2" flow, where sso-auth is the OAuth2 provider for sso-proxy and Google is the OAuth2 provider for sso-auth.

In a nutshell:

• If a user visits an sso-proxy-protected service (foo.sso.example.com) and does not have a session cookie, they are redirected to sso-auth (sso-auth.example.com).
  • If the user does not have a session cookie for sso-auth, they are prompted to log in via the usual Google OAuth2 flow, and then redirected back to sso-proxy where they will now be logged in (to foo.sso.example.com)
  • If the user does have a session cookie for sso-auth (e.g. they have already logged into bar.sso.example.com), they are transparently redirected back to proxy where they will be logged in, without needing to go through the Google OAuth2 flow
• sso-proxy transparently re-validates & refreshes the user's session with sso-auth
