Fingerprint login in 20.04

Question

I saw an OMG Ubuntu article about Ubuntu offering fingerprint support. But I do not see any such option in 20.04.

Is it really possible to login using fingerprint scan in 20.04? If yes, how?

Answer 1

What you need to do is to enable PAM Fingerprint authentication method.

1. Issue sudo pam-auth-update
2. Select Fingerprint authentication
3. Press Spacebar
4. Hit Enter

Answer 2

I partially solved it by upgrading firmware using

fwupdmgr upgrade

Now I get the option of login using fingerprint in settings->users. And I can get my fingerprints scanned there.

But I still can't really login with it. Nothing happens when I scan my fingers when the computer is locked.
