I am thinking about making an idle game.. But the current max amount of time a user can be idle is about 20? Minutes.. I don't know the exact time currently before they get kicked. Is there any way to bypass this or completely disable it?
You could use this,

and then check if their mouse has been idle for x minutes/seconds and then just make them jump if they have been idle for a certain amount of time.
