REMEDIATION

From Portal

1. Go to 'IAM'
2. In the menu, under 'Access management', choose 'Users' and choose the relevant user
3. Choose the 'Security credentials' tab
4. If access keys are used, make sure 'Console password' is disabled under 'Sign-in credentials'
5. If 'Console password' is used, make sure to disable any access keys under 'Access keys'

From TF
To disable an IAM user access key, set 'status' to 'Inactive':

resource "aws_iam_access_key" "example_access_key" {
	..
	user   = "USER-NAME"
	status = "Inactive"
	..
}

To delete an IAM user login profile (password), delete the following resource:

resource "aws_iam_user_login_profile" "example_user_login_profile" {
	..
}

From Command Line

aws iam list-access-keys --user-name USER-NAME
