Which statement regarding the AWS Single Sign-On service is NOT true?

The statement that AWS Single Sign-On (SSO) provides a decentralized administration experience is not true. AWS SSO is designed as a centralized access management service that enables you to manage user access to multiple AWS accounts and applications from a single location.

Centralized administration simplifies user and permission management, allowing organizations to enforce policies uniformly across all accounts, as well as provide audit capabilities in one central interface. This centralized approach is key to maintaining security and operational efficiency, especially in scenarios where organizations need to manage access for a large number of users and resources.

In contrast, a decentralized administration experience would imply that user management and access controls are fragmented across various accounts or applications, which contradicts the purpose and functionality of AWS SSO. AWS SSO focuses on streamlining and simplifying access management through a single administrative point, enabling better control and visibility over user permissions.
