Amazon Cognito vs Keratin AuthN: 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, Keratin AuthN is detailed as "Accounts and Auth Microservice in Go". AuthN manages a database of user accounts with sign-in credentials and related attributes. Your application frontend relies on AuthN for creating accounts, logging in, forgotten passwords, and session maintenance.
Amazon Cognito and Keratin AuthN can be categorized as "User Management and Authentication" tools.
