Monitoring: AWS account root user login
The AWS account root user has complete access to all AWS services and resources in an account. This identity is accessed by signing in with the email address and password that was used to create the account. As a best practice, we do not recommend using these credentials for everyday tasks.
Why should you monitor AWS account root user logins?
The AWS account root user should only be used in emergency situations. For example, in case you locked yourself out of an AWS account by a misconfigured IAM policy. In day-to-day use, the credentials for the AWS account root user should be kept in a safe place and not used. The use of the AWS account root user is a security risk and should be closely monitored.
