Install and Configure ThingWorx Server for SSO
* 
• If you’ve already installed and configured your Experience Service to use basic authentication, make sure you update your Experience Service to your target version (minimum version 9.3.0) before installing and configuring ThingWorx for SSO. For more information, see Configure SSO after Installation.
• You must have ThingWorx 8.5 or later in order to use SSO with the Experience Service.
Before installing the Experience Service, install the ThingWorx server and configure it to use SSO.
* 
When using SSO authentication, your Experience Service and ThingWorx must be installed on the same server.
