AWS Identity and Access Management (IAM) is a web service that enables Amazon Web Services (AWS) customers to manage Users and User permissions under their AWS Account. With it users can access features such as listing all users, retrieving documents for specified users and creating access keys.
AWS Identity and Access Management (IAM) enables developers to create and manage Users under the umbrella of their AWS Account. IAM is used in conjunction with other AWS products to control access to the AWS resources within an AWS Account. It uses RESTful protocol and responses are formatted in XML.
To help AWS customers handle credentials more securely, Amazon last week announced AWS Secrets Manager, a new service that allows AWS customers to store and retrieve passwords, OAuth credentials, binary data, and other types of secrets, such as API keys, via an API or the AWS CLI.
