    feat: add fprintd fingerprint authentication via greetd multi-stage PAM (v0.6.0)

    nevaforget released this 2026-03-29 13:47:57 +02:00 | 21 commits to main since this release

    Fingerprint auth was missing because moongreet rejected multi-stage
    auth_message sequences from greetd. With pam_fprintd.so in the PAM
    stack, greetd sends non-secret prompts for fingerprint and secret
    prompts for password — moongreet now handles both in a loop.

    • Replace single-pass auth with multi-stage auth_message loop
    • fprintd D-Bus probe (gio::DBusProxy) for UI feedback only
    • Fingerprint label shown when device available and fingers enrolled
    • 60s socket timeout when fingerprint available (pam_fprintd scan time)
    • Config option: [appearance] fingerprint-enabled (default: true)
    • Fix: password entry focus loss after auth error (grab_focus while
      widget was insensitive — now re-enable before grab_focus)
