Single signed-on in orchestrator robot configuration

In my workplace, we develop lots of robots for different departments. Due to security policy of our company, we are not able to apply a power user account that are able to access all the applications from different departments. and i found that only one user can connect to the robot machine, if we want to run the process with another user, we have to change to windows login credential every times, if there any solutions for this issues? it make me really confuse these days. thanks.
