Hardware • Re: Configuring Fingerprint Sensor on Debian with Thinkpad T14 Gen 1 AMD

Hello,
UPDATE: I managed to set-up the fingerprint reader but I would like for it to work differently during sudo prompt in the terminal. I would like to type Ctrl+C in order to choose input password with keyboard but whenever I press Ctrl+C it just cancels the entire thing
Can you please report the hardware involved and the software used to handle it ?
Oh of course!

I followed a guide by "jodarove" so all credit goes to him.

Basically, I used fprintd. Supported devices are listed here https://fprint.freedesktop.org/supported-devices.html

Check your device id. Run

Code:

lsusb
copy the id (the sixth column of the output) and search it on the website. In my case, it was 06cb:00bd (compatible)

Let's proceed to the installation:

1- Search for the package fprint

Code:

apt search fprint
2- Install fprintd

Code:

sudo apt install fprintd
3- Install the library/module PAM module

Code:

sudo apt install libpam-fprintd
4- Tell the system to use the fingerprint reader

Code:

sudo pam-auth-update
make sure "Fingerprint authentication" is selected, then select "Ok" to save.

5- Add or enroll your fingers print

Code:

fprintd-enroll -f [finger]
So you can do :

Code:

fprintd-enroll -f right-index-finger
Options for [finger] can be:

Code:

  left-thumb  left-index-finger  left-middle-finger  left-ring-finger  left-little-finger  right-thumb  right-index-finger  right-middle-finger  right-ring-finger  right-little-finger
6- Test it! run

Code:

fprintd-verify
enjoy!

Also, I greatly recommend upping the number of tries on the fingerprint from 1 to 2 or 3, because usually the sensor won't be able to read you fingerprint on the first try. you can do that by editing the /etc/pam.d/common-auth file and changing the max-tries part.
