Do You Let People Log Into Your Jagex Account?

I've been paying for people to do services over Parsec because I don't want anyone to log into my Jagex account. But after thinking, I'm starting to change my mind, but I wanted to ask the community first.

I know its probably self explanatory, but better safe than sorry, so I will ask: Is there anything I should know about letting workers log into my Jagex account? Obviously I will have all my other accounts locked down with bank pins, and usually I only order services that do not require bank access. After the service when I change the password, they are automatically force logged from the launcher? I will only be using highly-rated trusted shops on this forum.

Thanks!
