[Feature Request] Built in authentication based on room codes

[Mushin]

Is your feature request related to a problem? Please describe.
Remote access isn't currently secure (without VPN etc).

Describe the solution you'd like
Add simple authentication based on the room codes - only allow local users (or logged in plex user) to generate new room codes. Then remote users must input a correct room code to access the tool.

Being able to limit the users to just my Plex users would be ideal. I would rather not have someone poking around my library without my consent (shared media with Plex users = good enough consent in my book).
