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.
