Copper vs Satellizer: What are the differences?

What is Copper? Password-free signups. No social network required. People sign up with their number. You get verified info. 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.

What is Satellizer? Token-based AngularJS Authentication. Satellizer is a simple to use, end-to-end, token-based authentication module for AngularJS with built-in support for Google, Facebook, LinkedIn, Twitter authentication providers, plus Email and Password sign-in method. You are not limited to the sign-in options above, in fact you can add any OAuth 1.0 or OAuth 2.0 provider by passing provider-specific information during the configuration step.
