Sister using my profile on PS3 (Plex Pass Home question)

Hello!

Quick question about home profiles. So I've added my sister's account into my Home so that she can use Plex on her PS3 without having a Plex Pass (Not a managed user, her username). She told me that she needed my account's pin to be able to use the server, and now when she watches something, plexwatch reports it as me watching something and it messes with my watch history. I don't have a PS3 and can't be physically there. Is there a way to switch user profiles so I can walk her through how to switch?
