What capability does Platform Single Sign-on (Platform SSO) for macOS provide to users?

Platform Single Sign-on (Platform SSO) for macOS enables users to authenticate seamlessly with multiple applications by synchronizing local account credentials with an identity provider (IdP). This process simplifies the user experience by allowing them to access various resources and applications without needing to enter different credentials for each service. By leveraging an IdP, the system can securely handle authentication, enabling users to have a consistent login experience across compatible applications and services.

This capability is particularly valuable in enterprise settings where users interact with numerous applications daily. It increases productivity by reducing the number of times users must log in, mitigating the risk of password fatigue and increasing security through centralized credential management.

The other options do not fully capture the essence of Platform SSO. While access to multiple applications without re-signing sounds appealing, it mainly describes the results of proper SSO implementation rather than its core capability, which is to synchronize credentials. Similarly, storing local account credentials in the cloud or providing single device authentication across all platforms does not accurately reflect the specific function of Platform SSO, which focuses on seamless integration with an IdP for credential management.
