Explanation

Amazon Cognito is designed specifically to handle user authentication and authorization for web and mobile applications. An identity pool allows the app to authenticate users via different identity providers (such as social logins, enterprise logins, or custom authentication). Once authenticated, Cognito assigns roles and permissions through IAM roles, granting access to secured AWS resources. This is the most efficient and scalable solution for managing user authentication and access to backend resources in a mobile app.
