What does identity federation allow users to do in the context of SailPoint?

Identity federation in the context of SailPoint allows users to streamline their authentication process by enabling them to authenticate once and gain access to multiple systems or applications. This is particularly valuable in environments where users need to interact with various resources and services, as it enhances user convenience and reduces the need for multiple logins.

By leveraging identity federation, organizations can implement Single Sign-On (SSO) capabilities, which simplifies the user experience while also improving security. Users can utilize existing credentials to access different applications seamlessly without the hassle of entering credentials for each system individually. This process not only improves productivity but also reduces the likelihood of password fatigue, which can lead to weaker security practices.

In contrast, options that suggest limited access—such as only being able to log into a single system or requiring separate authentication for each domain—do not reflect the purpose of identity federation, which is designed to enhance accessibility and efficiency across multiple platforms. Similarly, sharing personal data across all domains does not specifically relate to the core function of identity federation but rather to concerns of data privacy and governance.
