Which AWS service relies on user pools and identity pools?

Amazon Cognito is the service that relies on user pools and identity pools to provide secure user authentication, authorization, and management.

User pools in Amazon Cognito allow you to manage user registration, authentication, and account recovery. They enable you to create a user directory that can scale to millions of users, allowing for features such as multi-factor authentication and customizable workflows.

Identity pools, on the other hand, provide access to AWS services for users, allowing for temporary, limited permissions using AWS credentials meant for accessing other AWS resources. This setup facilitates seamless integration of user authentication with authorization to access AWS services, making it easier to build scalable and secure applications.

The distinction lies in user pools focusing on user management, while identity pools handle authorization to AWS resources, both of which are critical for developing secure applications in the AWS ecosystem.

Other options like the AWS Identity Store, AWS IAM Console, and Amazon API Gateway do not utilize user pools and identity pools in the same way as Amazon Cognito does, as they serve different roles within the AWS security framework and service architecture.
