The 'root' user account is the most privileged user in an AWS account. AWS Access Keys provide programmatic access to a given AWS account. It is recommended that all access keys associated with the 'root' user account be removed. Rationale: Removing access keys associated with the 'root' user account limits vectors by which the account can be compromised. Additionally, removing the 'root' access keys encourages the creation and use of role based accounts that are least privileged.
