Single Sign-On (SSO) is designed to streamline the user authentication process by allowing users to log in once and gain access to multiple applications without needing to re-enter their credentials for each one. This enhances the user experience significantly, as it reduces the complexity involved in managing multiple usernames and passwords for different platforms.

In organizational settings, adopting SSO can lead to increased productivity because users spend less time logging in and can switch between tools and applications seamlessly. Additionally, it can improve security by reducing the chances of weak passwords being used or forgotten, as users only need to manage a single set of credentials.

The other options do not represent the primary function of SSO. For instance, requiring users to remember multiple strong passwords contradicts the goal of SSO, which is to decrease that burden. Similarly, restricting user access to a single application does not reflect the nature of SSO, which is to provide broad access across multiple applications. Lastly, ensuring complicated authentication processes runs counter to SSO's purpose of simplifying user logins.
