How to update Asset credentials?

My version is 2016.2 and I just tested per robot credential(monthly expiring) and works fine. But the thing is, same login is going to be used by 10 bots, so the plan is to move this log in from Windows creds to Assets, so the support team won’t have to change one by one every month. Thinks might look simpler than the previous for them though.

Thank you both for the help!
