Well, `sudo` is a *nix binary, so Linux and macOS are your most popular options here.
Fingerprint authentication for sudo was enabled by default on my Manjaro install after I enrolled a fingerprint so I guess popular Linux distributions configure it automatically. If yours doesn't, try the configuration methods on this page: https://wiki.archlinux.org/title/fprint or here: https://askubuntu.com/questions/1015416/use-fingerprint-auth... or consult your operating system's documentation.
The big difference is that you need "pam_fprintd.so" instead of "pam_tid". On Ubuntu (or derived, probably), running "sudo pam-auth-update" will allow you to configure fingerprint authentication without needing to manually edit system files.

a system. I don't know how gksudo and i3 work together on this, as visual sudo tools often try to block access to other windows.
If you're on Windows and want WSL with Windows Hello, there's this tool: https://github.com/nullpo-head/WSL-Hello-sudo which is a PAM library that will call into Windows Hello from WSL. Windows Hello should in turn support your fingerprint reader or other biometric authentication system configured for your PC.
