Amazon Cognito is a simple user identity and data synchronization service that helps securely manage and synchronize mobile app data.
Amazon Cognito lets you add user sign-up, sign-in, and access control to your web and mobile apps quickly and easily. Amazon Cognito scales to millions of users and supports sign-in with social identity providers, such as Apple, Facebook, Google, and Amazon, and enterprise identity providers via SAML 2.0 and OpenID Connect.
Work Offline
You can use the optional Amazon Cognito client SDKs to automatically create a local data store to cache user app data on the device. This means your app can keep reading and writing data regardless of the device connectivity state.
Store and Sync across Devices
With Amazon Cognito you can easily synchronize app data across all of an end user’s devices. Amazon Cognito manages the complexity of conflict resolution and intermittent network connectivity so that your app can always deliver a great user experience.
Control Access to AWS Resources
You can use the unique user identifiers that Amazon Cognito generates in your access policies to enable or restrict access to other AWS resources on a per-user basis.
Safeguard AWS Credentials
When you use Amazon Cognito, the service takes care of all the steps necessary to create a unique identifier for your app’s users and retrieve temporary, limited privilege AWS credentials.
Interaction with other Amazon services AWS Cognito can interoperate with AWS SES, AWS SNS, AWS Lambda, and more.
