fprintd-enroll -f "right-index-finger" "$USER"

check if it's working

fprintd-verify

Activate authentication

You will be able to enter the password or type enter for blank input and use fingerprint

NOTE : The PAM stack is by design a serialised authentication, so it is not possible for pam_fprintd to allow authentication through passwords and fingerprints at the same time.

See man page pam_fprintd(8) — libpam-fprintd — Debian unstable — Debian Manpages

For graphic apps , ligthdm, terminal

In /etc/pam.d/common-auth add at the beginning of the file

auth       sufficient pam_unix.so try_first_pass likeauth nullok
auth       sufficient pam_fprintd.so timeout=10

At boot, you will still to unlock the gnome-keyring with your password.
