Explanation:
AWS Identity and Access Management is a web service which allows organizations to manage
users and user permissions for various AWS services. Once the organization has created the IAM
users, they will have a separate AWS console URL to login to the AWS console. The console login
URL for the IAM user will be https:// AWS_Account_ID.signin.aws.amazon.com/console/. It uses

only the AWS account ID and does not depend on the group or user ID.
