Which benefit does Single Sign-On (SSO) provide in Identity Management?

Single Sign-On (SSO) provides significant benefits in terms of user authentication, making it easier and more efficient for users to access multiple applications with just one set of credentials. This streamlining of the authentication process enhances the user experience, as users do not need to remember and input various usernames and passwords for each application they access.

With SSO, when a user logs in to one application, they are automatically authenticated in other applications within the same ecosystem, reducing the need for repeated logins. This not only improves security by reducing the chances of password fatigue—where users may create insecure passwords or reuse passwords across different systems—but also enhances productivity, as users can swiftly switch between applications without interruption.

The other options relate to specific technical aspects that do not capture the primary essence of what SSO aims to improve within identity management. Enhanced data storage and increased API throughput are more related to system efficiency and performance, while reduced system latency does not directly correlate with authentication processes. Thus, the focus on improved user authentication precisely encapsulates the core advantage of implementing SSO in an identity management framework.
