Copper vs sso: What are the differences?

Copper is a service for developers who want a seamless, always-improving signup and signin flow in their websites and iOS apps. We remove friction so more people become and remain users, while makers ship faster and maintain less code. On the other hand, sso is detailed as "Buzzfeed's single-sign-on authentication proxy". 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.
