Biopass - An alternative to Howdy

Modern multi-modal biometric login for Linux — face and fingerprint, with GUI management.

---

Why Biopass?

While Windows Hello provides a seamless multi-modal biometric experience (Face, Fingerprint, PIN) on Windows 11, Linux has historically lacked a modern, unified equivalent. Biopass was developed by @phucvinh57 and @thaitran24 to fill that gap — see the comparison with Howdy below.

Comparison

Feature	Biopass	Howdy
Authentication methods	Face + Fingerprint	Face only
User Interface	Modern GUI for management	Command-line interface only
Configuration	GUI	Manual
Face Anti-spoofing	IR camera + Embedded AI model	IR camera only

Installation

• Debian and RPM package: https://github.com/TickLabVN/biopass/releases
• AUR package: https://aur.archlinux.org/packages/biopass-bin
• System sign-in setup uses distro-managed PAM configuration when available (for example pam-auth-update on Debian/Ubuntu): docs/PAM.md
• Interactive polkit authentication setup: docs/Polkit.md
• IR camera setup guide

Features

• Authentication: User can register multiple biometrics for authentication. Authentication methods can be executed in parallel or sequentially.
  • Face:
    • Recognition
    • Anti-spoofing
      • With AI model
      • With IR camera
  • Fingerprint
