Hi @TharmaKS ,
Yes, it is possible. When you provision a robot, you have in that modal a checkbox “Create another”.
If you check it you will have the same key and the same machine. You will have to change only the Username and password.
Another way would be, if you already have a robot provisioned, go to More actions and click Duplicate and it will add another robot with the same key and the same Machine name.
Please note that the two Robots(same key, same machine name, different usernames) have to be on a Windows server machine in order to run in the same time.
And here is the documentation on how to set up the server:
