Assumptions:
- You have
fprintdinstalled already, following the Arch wiki. - You have enrolled your fingerprints.
Install polkit:
sudo pacman -S polkitCreate a polkit-1 file in pam.d:
sudo nano /etc/pam.d/polkit-1#%PAM-1.0
auth sufficient pam_fprintd.so
auth include system-auth
account include system-auth
password include system-auth
session include system-authTesting:
pkexec whoamiYou should see the system authentication prompt and it should prompt for your fingerprint as well.
To Bitwarden:
In Settings -> Security, check “Unlock with system authentication”. Then close the settings and lock the vault with either the menu item or Ctrl+L.
You should see “Unlock with system authentication” above “Unlock with master password”.
Give it a click. You should get the same prompt as before from pkexec and it should include the fingerprint request.
To 1Password:
In Settings -> Security, check “Unlock using system authentication service”. Then repeat the prior steps for Bitwarden.
This all just worked for me, so I have no idea what to do if it goes wrong for you, dear reader.
