Exam AWS Certified Cloud Practitioner topic 1 question 533 discussion

C. Amazon Simple Notification Service (Amazon SNS) is the AWS service that the company should use to meet this requirement. Amazon SNS is a fully managed service that enables you to publish messages to a variety of endpoints, including SMS text messages. With Amazon SNS, the company can distribute one-time passwords to its customers worldwide via SMS text messages, ensuring the security of the business application with MFA. AWS Identity and Access Management (IAM) is a service that enables you to manage access to AWS resources. It provides authentication and authorization mechanisms for AWS services and resources, but it does not provide a messaging service to distribute one-time passwords via SMS text messages.
