Can't use several auth ways

**enthusasist** · 2 Weeks Ago

Hello! Sorry if there’s already such a topic, couldn’t find it.
Could you please tell if there is a way to use different authentication ways at the same time?
For example if I add a fingerprint (with fprintd 1.9.42 and pam-auth-update) I can only select to use:

only password
only fingerprint
password and then fingerprint

But I want to use fingerprint OR password (what I prefer at the moment),
or at least fingerprint and if it doesn’t work, then password.
And similar situation with camera auth (faceID). I installed howdy 2.6.1, added my face and it even works when I want to use sudo it recognizes me, but when I try to login to my OS user it doesn’t recognize me and the worth thing is that it dowsn’t even ask password, just block me.

My OS is: Kubuntu 22.04.4 LTS (Jammy Jellyfish)
Kernel: 6.5.0-28-generic #29~22.04.1-Ubuntu
plasmashell: 5.24.7
Qt: 5.15.3
KDE Frameworks: 5.92.0
kf5-config: 1.0

Laptop:
Lenovo ThinkPad T14s Gen 4 AMD (21F9S0T900)

Thanks in advance!

May I ask what you're trying to protect with either of those measures? Because system authentication methods are trivial to bypass when someone has physical access to your computer, especially if you don't use volume encryption. I have frankly stopped caring about my local password on Linux machines, only the LUKS passphrase matters (to me anyway).

Well, fortunately(or not), my little child does not yet know how to bypass system authentication methods, but can easily log into an unpassworded account and, for example, accidentally break something in remote production.
