Ember Cognito Integration

ember-cognito is an Ember Addon that integrates the Ember.js authentication library, ember-simple-auth, with AWS Amplify and AWS Cognito User Pools. It provides a custom authenticator and a service to access Amplify authentication methods, streamlining user authentication in Ember applications using AWS's managed identity service. The current stable version is 4.0.2, released in December 2025. This addon has a consistent release cadence, frequently updating to support newer Ember.js and AWS Amplify versions. A key differentiator is its seamless integration with ember-simple-auth, abstracting the complexities of interacting directly with the AWS Cognito SDK via Amplify, and providing helpers for common authentication flows like sign-up, confirmation, and session management. It also requires specific configuration for modern Ember v2 addons and Embroider compatibility.
