AWS Identity and Access Management (IAM) is a web service that helps to securely control access to AWS resources. IAM is used to control who is authenticated (signed in) and authorized (has permissions) to use resources. When an AWS account is first created a single sign in identity (called the AWS account root user) that has complete access to all AWS services and resources in the account is also created, this identity is accessed by signing in with the email address and password used to create the account.
