Works on my Thinkpad.

april ,

It depends if you're lucky with the exact model of sensor you have

r0bi ,

Werks on my Thinkpad X13

Pantherina ,

Same on Thinkpad T495

The one on my ThinkPad started working when I upgraded to KDE 6 / Wayland. I was pretty happy about that.

Oooh I gotta try that

pete_the_cat ,

Oh nice, I have a Carbon X1. I knew that fprintd has worked for a while, and has allowed me to enroll fingerprints, but has never successfully worked for authentication.

That was my issue too, also on an X1C (gen 9)

archer ,

For me it only works for signing in after sleep, but not for anything else (T490). Does your Thinkpad work better/in more ways?

Same, I can't use it in the terminal or anything like that, but it didn't work at all before.

Twitches ,

I understand wanting to use this, but, fingerprint reader is so I secure I usually avoid it.

thanks_shakey_snake ,

Is it really less secure than a password? How so?

If it's compromised you can't change it for one

Also you can't be legally forced without a warrant to give a password but biometric data you can be legally forced without a warrant to give up

foggy ,

Lol let's take the kid gloves off, shall we?

Fingerprints, as a means of authentication, is just straight up not secure.

Bassman1805 ,

Man, I knew fingerprint encryption was bad but that is nuts.

PumpkinEscobar ,

Fwiw they’re able to do the same thing by the sound of someone typing a password across the room. Not advocating for fingerprints or anything, just these exotic hacks are everywhere

foggy ,

This one's my fav

marcos ,

The thing is, one of those attacks requires you to type your password. The other requires you to touch something.

flambonkscious ,

...my memory was that this only worked after the routine had been trained on your typing idiosyncrasies

aberrate_junior_beatnik ,

A fingerprint is a password you leave a copy of on everything you touch.

MonkderDritte ,

Biometric data can be used as login but is unsuitable as password, since it can't be changed once compromised.

With a password you can have an exact binary comparison. Either you supplied the correct password or you didn't.

But with biometrics you just have an approximation because your fingerprints change slightly due to the position in which you hold them, your health, humidity, pressure and probably other stuff I'm not thinking of. So the sensor can only say that it's like 95 % or whatever sure that it got the correct fingerprint. And this uncertainty makes it much easier to exploit.

And your fingerprint is not secret. You leave it all over the place. Especially on devices you use every day. And your fingerprint can (and will) be taken without your consent. And you cannot change your fingerprint if it gets compromised.

All those spy movies showing how trivial it is to circumvent biometric security have in common that whatever method they used was realistic.

Twitches ,

Lol my hands are jacked from physical labor and health, scars on my fingers, dry skin, my thumb print only works only 50% of the time anyhow.

henfredemars ,

I use it if only because my wife won't use passwords on her devices. We aren't even at step one for device security. I'll take what I can get, or what she's willing to work with.

acockworkorange ,

Can you get to 2FA with a 4 digit PIN, at least?

Linux is just more secure and keeps you from doing a stupid mistake.
