So I've been having this issue for a while now. I signed in my own plex account (that runs my server) a while back on to my friend's Xbox 360 and Xbox One but now I don't want him to be able to use these devices from my account. I've tried removing the devices from Plex Web several times, changed my password/removed all devices connected several times, removed both of the devices from the "Single Sign On Authentication" in the settings, but lo and behold he's able to still use my server via my account on both devices. I didn't think it would be this difficult to remove someone from my server. What do I do?
I do not have an XBox to help out, but I will move this question to the XBox section. You might get an answer there.
Have you tried changing your Plex password or setting a PIN?
Did you sign to your Plex server under HIS live ID or your own live ID on his box?
If under your Live ID then change or set a pin/password so he can't login to it.
Worst case you could check the logs to get his IP address. Then block the C range via your firewall.
