There should not be any login pop up for user again in Unified Service Desk, if the user is already logged in CRM on the same machine.

Plus there should be a way to remember the credentials entered while opening Unified Service Desk Change Credential window. In this way if user opts to remember the credentials then there should not be any pop up asking user to login every time the Unified Service Desk opens.

Thanks for the idea. There are no new feature investments on USD and we recommend existing customers to plan to migrate to Customer Service Workspace (CSW) app, which is a web based app with OC and unified routing supported. Our future roadmap and investments are targeted at CSW for all agent/supervisor experiences specific to Customer Service. For any questions, feel free to reach out to Fast Trach or Customer Success teams.
