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

1
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
