Which AWS service should the company use to meet this requirement?

Explanations:

Amazon EventBridge is primarily used for event-driven applications and does not handle the distribution of one-time passwords via text messages.

AWS Identity and Access Management (IAM) is used for managing access to AWS resources and does not directly facilitate sending one-time passwords to customers.

Amazon Simple Notification Service (Amazon SNS) is designed for sending notifications, including SMS messages, making it suitable for distributing one-time passwords.

Amazon Connect is a cloud-based contact center service and is not intended for sending SMS messages or handling multi-factor authentication processes.
