Amazon Cognito Developer Resources

Amazon Cognito Workshop
In this workshop, we will deep dive into Cognito and build out an authentication solution for a sample retail store. We will be working with Amazon Cognito user pools for API Authentication for a Hosted UI, Amazon Cognito user pools SDK with AWS Amplify, and the Amazon Cognito identity pools SDK.

Amazon Cognito user pools (Developer Guide)

Follow these steps to set up and configure a user pool for the first time with the Amazon Cognito console

Set up the sample app: iOS | Android | JavaScript (Angular 2)

Amazon Cognito identity pools (Developer Guide)

Provides an overview and steps of Amazon Cognito identity pools for creating identities or setup user authentication with federated social or SAML-based identity providers.

Set up a sample app: iOS | Android

Integrate identity pools with user pools (Developer Guide)

Connect your users and apps to other AWS services.

Synchronize application data across devices

If you're new to Amazon Cognito Sync, use AWS AppSync. AWS AppSync is a service for synchronizing application data across devices. It enables user data like app preferences or game state to be synchronized. It also extends these capabilities by allowing multiple users to synchronize and collaborate in real time on shared data. For existing customers of Cognito Sync, here is a reference to get started with Amazon Cognito Sync.

Implement passwordless authentication with Amazon Cognito

Passwordless authentication improves security, reduces friction and provides better user experience for end-users of customer facing applications. Amazon Cognito provides features to implement custom authentication flows, which can be used to expand authentication factors for your application. This solution demonstrates several patterns to
support passwordless authentication and provides reference implementations for these methods:

• FIDO2: AKA WebAuthn; sign in with Face, Touch, YubiKey, etc.
  
• Magic link sign-in: sign in with a one-time-use secret link that's emailed to you (and works across browsers).
  
• SMS-based step-up authentication: let an already signed-in user verify their identity again with a SMS One-Time-Password (OTP) without requiring them to type in their password.

The reference implementation of each of these authentication methods uses several AWS
resources. This solution contains both CDK code (TypeScript) for the back end, as well as front-end code (TypeScript) to use in Web, React and React Native to help developers understand the building blocks needed and expand and adjust the solution as necessary.
