Wow thanks. I just learned something new.

This is now my favourite way to grab the WiFi password.

Why has it never occurred to me that I might be able to use a QR code? I always do `sudo cat /etc/NetworkManager/system-connections/TheSSID.nmconnection | grep psk`, type in my root password and then re-type the passphrase manually on my phone. The amount of time this is going to save me…

I was always aware my phone has an option to scan a QR to connect to WiFi, but I never thought to look up the QR spec for it. I had no idea nmcli had this functionality either, though I have used qrencode a lot for TOTP and WireGuard.
