VNC has had some changes in Raspbian Bookworm. Many VNC clients won't connect anymore due to changes in authentication. Here's how to get this working.

FIrst, run `sudo raspi-config` on the command line or in the Raspbian graphical desktop find the settings app. In either, under Interfaces, enable VNC.

Then, you can use one of the updated VNC clients, currently TigerVNC and RealVNC seem to work as of today.

Or, you can use other clients (like Reminna) but you have to disable auth on the Pi first. To do that, edit `~/.config/wayvnc/config` and add `relax_encryption=true` and change `enable_auth` to `false`. Obviously don't do this if your Pi is reachable from the outside world.

Hopefully Reminna will get an update soon to allow auth to be re-enabled.
