InformationThe '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.
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.
SolutionPerform the following to delete or disable active 'root' user access keys
Sign in to the AWS Management Console as 'root' and open the IAM console at https://console.aws.amazon.com/iam/.
Click on <Root_Account_Name> at the top right and select My Security Credentials from the drop down list
On the pop out screen Click on Continue to Security Credentials
Click on Access Keys (Access Key ID and Secret Access Key)
Under the Status column if there are any Keys which are Active
Click on Make Inactive - (Temporarily disable Key - may be needed again)
Click Delete - (Deleted keys cannot be recovered)
