AWS IAM password policy does not have a lowercase character


Password policies are used to enforce the creation and use of password complexity. Your IAM password policy should be set for passwords to require the inclusion of different character types. The password policy should enforce passwords contain at least one lowercase letter, this increases security, especially from a brute force attack.

Fix - Runtime

AWS Console

To change the password policy in the AWS Console you will need appropriate permissions to View Identity Access Management Account Settings.

To manually set the password policy with a minimum length, follow these steps:

  1. Log in to the AWS Management Console as an IAM user at https://console.aws.amazon.com/iam/.
  2. Navigate to IAM Services.
  3. On the Left Pane click Account Settings.
  4. Select Requires at least one lowercase letter.
  5. Click Apply password policy.

CLI Command

To change the password policy, use the following command:

aws iam update-account-password-policy --require-lowercase-characters
