Automatically Log Out Idle Users

[Nerd-Ecke]

Hy

I have now spent a whole evening with the documentation but can't find a solution.

I want that when I am idle or log on to another device, the other session logs off.

Purely related to the browser session sitting on the client, not the user on the host system.

Example:
I log in at work then go home and log in at home then no one at work should have access to the session without entering the user and password again.

I have already tested the following:
nano ~/.vnc/kasmvnc.yaml

user_session:
session_type: exclusive
new_session_disconnects_existing_exclusive_session: true
concurrent_connections_prompt: false
idle_timeout: 300

This works so far but I can simply reconnect to the other session.

Are there any solutions?
