Which AWS service can the company use to make this integration?

Explanations:

AWS Directory Service is primarily used for setting up and managing Microsoft Active Directory in the AWS Cloud, not for integrating social media logins.

AWS Identity and Access Management (IAM) is used for managing access to AWS resources, but it does not provide functionality for social media authentication.

Amazon Cognito is designed for user authentication and can easily integrate with social media identity providers like Facebook, Google, and Amazon, allowing users to log in using their social media credentials.

AWS IAM Identity Center (AWS Single Sign-On) is used for managing access to multiple AWS accounts and business applications, but it does not focus on social media login integration.
