# nullpo-head/WSL-Hello-sudo

Let's sudo by face recognition of Windows Hello on Windows Subsystem for Linux (WSL). It runs on both WSL 1 and WSL 2. This is a PAM module for Linux on WSL.

## What it is
A Linux PAM module plus companion Windows CLI app that lets WSL users authenticate sudo and other PAM-based logins via Windows Hello biometrics (face, fingerprint, or PIN). Written in Rust and works on both WSL 1 and WSL 2.

## Use cases
- authenticate sudo with face recognition on WSL
- use Windows Hello fingerprint for Linux commands in WSL
- replace sudo password prompts with biometric login
- add biometric authentication to su and other PAM apps in WSL
- avoid typing passwords in Windows Subsystem for Linux

## When to choose
- you use WSL daily and want faster, more convenient sudo authentication
- you want biometric (face/fingerprint) login for Linux tools inside WSL
- you prefer a PAM module over a sudo fork so all PAM-aware apps benefit

## When to avoid
- you don't run Windows or WSL
- you need guaranteed security - the project ships with no warranty and should be used at your own risk
- your distro lacks PAM or you can't modify PAM configuration
- you need a solution maintained with frequent updates - the latest release is from 2023
