Amazon IAM

Amazon IAM is an AWS Identity and Access Management security service that makes it easy to control who has access to AWS resources so they can't do more than what was intended.

Amazon IAM is a web service that provides authentication and authorization for AWS resources. It uses AWS credentials to provide secure access to AWS resources. The service is built on top of IAM roles and permissions, which are in turn based on user identity and group membership information.

This service can be used by developers to create and manage their own IAM configurations, or it can be used as a fully managed service.Users can also use Amazon Cognito User Pools to manage identities for their applications, including sign-up with social providers like Facebook or Google.
