Description

IAM password policies can prevent the reuse of a given password by the same user. Preventing password reuse increases account resiliency against brute force login attempts.

How to fix?

Set the aws_iam_account_password_policy password_reuse_prevention field to 24 to ensure the previous 24 passwords cannot be reused.

Example Configuration

resource "aws_iam_account_password_policy" "example" {
  password_reuse_prevention = 24
  # other required fields here
}
