How can a System Administrator configure Single Sign-On (SSO) in Smartsheet?

To configure Single Sign-On (SSO) in Smartsheet, the process involves essential steps that are specifically laid out in the platform's Admin Center. By navigating to the Security settings within the Admin Center, a System Administrator can enable SSO and supply the required authentication credentials. This centralizes user management and enhances security by allowing users to log in to Smartsheet using their existing organizational credentials, thus streamlining access and reducing password fatigue.

The other options, while they involve aspects of user management and security, do not align with the specific requirements for SSO configuration. Integrating with third-party apps, while useful for extending functionality, does not address the particular setup for SSO within Smartsheet directly. Creating additional user profiles for each user would complicate the user management process rather than simplifying it with SSO. Enabling two-factor authentication adds a layer of security but does not facilitate the SSO configuration, which is focused on single login sessions through organizational identity providers. Thus, the correct answer distinctly highlights the designated method for setting up SSO within Smartsheet.
