Description AWS Identity and Access Management (IAM) is a web service that helps you securely control Access to AWS resources.
Then securely lock away the root User credentials and use them to perform only a few account and service Management tasks..
Instead, adhere to the best practice of using the root User only to create your first IAM user.
We strongly recommend that you do not use the root User for your everyday tasks, even the administrative ones.
This Identity is called the AWS account root User and is accessed by signing in with the email address and password that you used to create the account.
When you first create an AWS account, you begin with a single sign-in Identity that has complete Access to all AWS services and resources in the account.
You use IAM to control who is authenticated (signed in) and authorized (has permissions) to use resources.
