2.Install packages

  • 2.1 Packages for Fingerprint GUI for Ubuntu 14.04, 16.04, 17.10, 18.04 and any distribution based thereupon

  • 2.2 Install fprintd (for me in device 138a:0090)

    • read the guide: Validity and libfprint in github

    • for ubuntu/linuxmint

      sudo apt install fpirntd
      sudo add-apt-repository -y ppa:3v1n0/libfprint-vfs0090
      sudo apt update
      sudo apt install libpam-fprintd

    • for archlinux

      sudo pacman -S fprintd
      yaourt -S libfprint-vfs0090-git

3.Enroll your finger print

  • add your signature for a finger (touch your finger device)

    fprintd-enroll
    • ! use sudo fprintd-enroll may have some bug

  • if not work

    for finger in {left,right}-{thumb,{index,middle,ring,little-finger}; do fprintd-enroll -f "$finger" "$USER"; done

    • e.g for finger in {left,right}-{thumb,{index,middle,ring,little-finger}; do fprintd-enroll -f "right-index-finger" "kevin"; done

    • ! here has a bug, you may need to add 10x4 times to add finger signature

4.Login configuration

  • 4.1 For linuxmint

    • Add pam_fprintd.so as sufficient to the top of the auth section of /etc/pam.d/runuser

    auth            sufficient      pam_rootok.so
