Fingerprint Settings

These are the steps to enable the Fingerprint authentication resources on:

• Thinkpad X1 - Gen.7
• Elementary OS 6 - Odin

This fingerprint authentication process enables the authentication on:

• Login screen (identified by an icon on the right side of the password input)
• Terminal (identified by text)
• Root actions on desktop (NOT identified visually, but it works just by placing your finger on the reader)

1. Install necessary packages

sudo apt-get install fprintd libfprint-2-2 libfprint-2-tod1 libpam-fprintd

2. Enroll the first (right index) finger in fprintd

fprintd-enroll

To enroll additional fingers, run the following

fprintd-enroll -f [finger-id]

Finger IDs: 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

3. Activate the fingerprint pam module

sudo pam-auth-update

Select the Fingerprint modules as you need. By default I enabled the following:

• Fingerprint authentication
• Unix authentication
• Register user sessions in the systemd control group hierarchy
• GNOME Keyring Daemon - Login keyring management
• Inheritable Capabilities Management

4. Log out

Log out from your account or restart your device.
