Simplicity

A simple way to implement Facebook and Google login in your iOS apps. Simplicity can be easily extended to support other external login providers, including OAuth2, OpenID, SAML, and other custom protocols, and will support more in the future. We always appreciate pull requests. Facebook and Google's SDKs are heavyweight and take time to set up and use. You can use Simplicity and only have to manage one SDK for logging in with an external provider in your app. Simplicity adds just 200KB to your app's binary, compared to 5.4MB when using the Facebook & Google SDKs. Simplicity is also extensible, and already supports other login providers, like VKontakte (the largest European social network) and generic OAuth providers. Simplicity is maintained by Stormpath, an API service for authentication, authorization, and user management. If you're building a backend API for your app, consider using Stormpath to help you implement a secure REST API.
