What service allows the secure creation or connection of workforce identities across AWS accounts?

AWS IAM Identity Center is designed specifically to facilitate the secure creation and management of workforce identities across multiple AWS accounts. This service provides a centralized way to manage user access and permissions, allowing organizations to streamline their identity management processes while ensuring compliance with security policies.

By utilizing AWS IAM Identity Center, organizations can easily create and manage users, groups, and roles, and assign permissions to these identities across various AWS accounts without needing to replicate identity data in each account. This not only enhances security through centralized management but also simplifies the user experience by offering single sign-on capabilities for users accessing multiple AWS accounts.

Other services such as AWS Directory Service and AWS Cognito may also support identity management, but they serve different purposes. AWS Directory Service is primarily aimed at integrating with on-premises Active Directory or providing a managed directory environment, while AWS Cognito focuses on user authentication for applications, particularly for mobile and web applications. AWS Single Sign-On (SSO) is related but does not encompass the full extent of identity creation and management functions as effectively as AWS IAM Identity Center does.

Therefore, AWS IAM Identity Center stands out by providing a comprehensive solution for securely managing workforce identities across multiple AWS accounts.
