Enabling fingerprint login in Xubuntu

I have looked around and found that Ubuntu supports fingerprint reading, but I can't find any information for Xubuntu. I have tried to find the equivalent of Settings → Users → Authentication & Login, but I haven't had any luck.

How can I enable my laptop's fingerprint reader in Xubuntu 21.10?

My laptop is an HP ProBook 650 G2.

This probably wont be a solution to the question but it might be help someone like me who got there multiple times trying to solve similar issue.

I managed to get finger print working on Samsung 400B laptop with Linux Mint Xfse using fprintd. First probably is worth to check supported device list. My one was listed there.

Device-3: 2-1.5:4 info: AuthenTec type: <vendor specific> driver: N/A rev: 2.0 chip ID: 08ff:168a

(In Mint you can find it under "System Reports" > "System information")

Installation:

apt-get install fprintd libpam-fprintd

Then add enroll (register) your finger print:

fprintd-enroll <USERNAME>

you should be asked to swipe your finger (note what you need to do that multiple times)

To verify fingerprint:

fprintd-verify <USERNAME>

Then what I needed to do is to modify /etc/pam.d/common-auth and add this line:

auth sufficient pam_fprintd.so

I try few places to put it at. I noticed if I add it as last command it asked for password and then I needed to verify with fingerprint as well. That can be useful for extra security, but that not was my goal. So I added it to the beginning:

# here are the per-package modules (the "Primary" block)
auth sufficient pam_fprintd.so
auth    [success=1 default=ignore]  pam_unix.so nullok
# here's the fallback if no module succeeds

and that gave me finger-print first and if it succeeds then I'm in, but if it fails 3 times then I can enter password to authenticate.

I have tried fprintd, it is working well with my hp pavalion dv4-1502tu notebook. I am running zorin os Lite.

But make sure your device should be listed here

To check your fingerprint reader details run below command in terminal

lsusb | grep Finger

Sample output is like below

Bus 003 Device 003: ID **138a:0001** Validity Sensors, Inc. **VFS101** Fingerprint Reader
