Which of the following is NOT a reason to use an embedded guide?

Using an embedded guide is designed to enhance user experiences, streamline processes, and allow for centralized updates. These features benefit users by making systems more intuitive, simplifying workflows, and ensuring that updates to the guides can be made in one place rather than scattered throughout different resources.

Facilitating single sign-on, however, is typically related to authentication processes and user access management rather than the benefits of using embedded guides. Embedded guides focus more on helping users understand and navigate processes rather than on managing user credentials or access to the system. Therefore, this option does not align with the primary purposes of implementing embedded guides.
