- Lemmy code of conduct: https://join-lemmy.org/docs/code_of_conduct.html
2. Be civil
- Understand the difference between a joke and an insult.
- Do not harrass or attack members of the community for any reason.
- Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
- Bigotry will not be tolerated.
- These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
3. Post Linux-related content
- Including Unix and BSD.
- Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of
sudo in Windows.
- No porn. Even if you watch it on a Linux machine.
4. No recent reposts
- Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.
Please report posts and comments that break these rules!

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.
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.
