Download the .deb from their downloads page and run it, just like you would either a .exe on Windows. Their instructions list that as an option further down on the page. Should be higher up imo
I will abandon windows when the games can all be played on Linux properly.
I feel you there. I'm just about at that point, although I also need better support for music software (FL studio, VSTs, etc) and hardware before I can fully switch.

Passkeys are asymmetric, meaning that the server only ever sees your public key. If the server gets breached, then only your public key is leaked, which isn't a big deal. Functionally, it's almost identical to SSH keys.
Open Media Vault (OMV)! I was given a used QNAP NAS, but didn't want to use their OS. TrueNAS has higher system requirements than what I had and Unraid is paid. OMV has been a dream! Having the flexibility of a full Debian OS, but also with the prepackaged software I need, it amazing. Plus, I love the web UI. At the time of writing this, I have 12TB of usable space with 3 months of uninterrupted uptime.
Check out this plugin for it!
