so ive been looking into a Yubikey because i want 2FA on all of my accounts. however on yubicos website it says it supports linux. but the documentation is confusing and i want the Authentication app to setup my Yubikey on my main OS (NixOS) it seems that yubico only supports ubuntu, which i tried using in distrobox but with no success. so i looked on flathub and found this app however it gets me kinda spooked that the app is made by the community. is it safe to use my yubi key with? and if not does anyone have any idea how to compile from source, which btw im kinda a noob at compiling from source which i know is ironic because i run nix.
