If you're using Network Manager, you can also just run this command!

  nmcli dev wifi show-password

You get the password as text, and a nice in-terminal QR code.

That is actually quite cool. I wonder how many command line tools could take advantage of such a feature. Like, I don't know, upload a file somewhere and show a one-time QR code to transfer that file into your phone or something.

There is this app who is doing kinda that https://github.com/sz3/cfc

I use QR codes in my DIY VPN script https://GitHub.com/fazalmajid/edgewalker to ease setup of WireGuard and IPsec VPN clients like iPhones.

Recent Plasma Desktop lets you show a network QR code right from the right-click context menu.

I actually lied, if you click the NetworkManager applet in Plasma, there's a direct QR code button visible without having to use the context menu at all.

Wow! Had no clue this was possible! Thank you!
