Amazon Cognito vs OmniAuth: What are the differences?
Developers describe Amazon Cognito as "Securely manage and synchronize app data for your users across their mobile devices". You can create unique identities for your users through a number of public login providers (Amazon, Facebook, and Google) and also support unauthenticated guests. You can save app data locally on users’ devices allowing your applications to work even when the devices are offline. On the other hand, OmniAuth is detailed as "OmniAuth is a flexible authentication system utilizing Rack middleware". OmniAuth is a Ruby authentication framework aimed to abstract away the difficulties of working with various types of authentication providers. It is meant to be hooked up to just about any system, from social networks to enterprise systems to simple username and password authentication.
