Another tip: On Android phones, Tasker can be used to automatically activate Wireguard tunnels to your own or a commercial VPN host. Taskernet.com has one project that activates WG when off specific wifi networks, and another that I wrote that allows you to activate a tunnel on demand only when you open specific apps. Great if you want to access a home server occasionally (without detectable open router ports) or want an extra layer of security when running a financial app.
Biden definitely learned something from watching the Republicans screw Obama again and again.
