title: How to use JWT in case of UI application is using SSO
body: <p>I have Web APIs built in .NET 6 and has JWT authentication in place for security. As far as I know, UI client application uses to send userName/password as first request to API and then API will validate the credentials and send response back to client with JWT token, from there client application uses that token for any subsequent requests. In my case, client will not be sending explicit userName/password as it's UI is being launched by  SSO. So in this case my API will not receive user validation request and no JWT will be generated. I am confused now, how and when will I generate token for client to use other API endpoints for fetching data from my API. Any idea/suggestions please.
  Or shall I change the authentication process to any other which is suitable to my scenario. Thanks</p>
