Switching plex accounts in Rasplex.

Hi there.
I would like to know if there is an easy and fast way to switch between plex accounts in Rasplex.
I am not a premium plex user, and i have setup a second plex account with access to my libraries so that my parents can have their own “unwatched” list.
Navigating to options and pairing their plex account through another device would be impossible for them.
What are my options?

The only option without the PlexPass feature of Plex Home would be signing in to Plex through Preferences->System->Plex. They can sign in using their username and password without having to use the PIN method on another device.

Regards

I walked my parents through the signin options over the phone and just had them read me the pairing code. Then I paired it for them remotely.
