you clarify this example (I already read the article you linked earlier and it doesn't go into details on this point) - if I hire a freelancer and add them with "Limited" permissions to, say, some hosting servers, will that freelancer at any time be able to actually SEE the passwords as they log into that hosting server?

I'm not clear on how they will log into a site using RF without seeing the password and being able to copy/paste it somewhere if they chose to. Which would defeat the purpose of using this app for me as I would still need to change passwords when finishing a project with a temporary worker. Thanks.
