Explanation

The AWS Management Console is the correct service to change an AWS account root user password because:

• AWS Management Console: This is the web-based interface where users can manage their AWS account settings, including changing the root user password. The root user is the primary account owner with full administrative access to all AWS services and resources.

• AWS IAM Identity Center: This service provides single sign-on (SSO) access to multiple AWS accounts and business applications, but it doesn't manage root user passwords.

• AWS Secrets Manager: This service is designed to store, rotate, and manage secrets like database credentials, API keys, and other sensitive information, but not root user passwords.

• AWS Security Hub: This is a security service that provides a comprehensive view of your security posture across AWS accounts, but it doesn't handle password management.

Key Point: The root user password can only be changed through the AWS Management Console by signing in as the root user and navigating to the account settings or security settings section.
