Do you need a password on your gaming machine? What is your threat model?

Even if there’s nothing on the machine itself you care about, don’t forget about everything else it can talk to on your local network.

So the scenario is: somebody breaks into the house, sits down at the gaming PC, and is able to poke around the local network because the gaming PC has no login password?

I wouldn't say it's THE scenario, but it's A scenario.

There's a reason IEEE says it's best practice to give IoT devices a strong username and password and to segment them away from the rest of your network, right?
