SMS second factor is so bad! The really dumb thing in my opinion is the place that uses SMS to factor the most is banks. Now how dumb is that?
Comment on Passkeys might really kill passwords
Spotlight7573@lemmy.world 9 months agoIt’s probably overkill for most people but I would love to have a system that lets me choose what combination of factors together work to login rather than just ‘password and something else’. Something like A,B,C are on the account and you can use A+B or B+C to login. It’d be great for those who don’t necessarily want to trust SMS-based one-time passwords (due to SIM swapping, theft, etc) if we could require something else along with it.
That said, the way passkeys are typically used satisfy multiple factors at once:
Password to unlock your password database that stores your passkey: something you know, the password + something you have, the database
Biometric to unlock your phone that has your passkey: something you are, fingerprint or face + something you have, the phone

In the EU they have to use something stronger if available. SMS is only used if requested by the user.

I wish it were that way here in the United States. But sadly, nope.

Banks are certainly behind the times and ‘bank-grade security’ is a joke in terms of what authentication methods they offer. I understand that they are slow to change anything though.

My crypto wallet is more secure than my bank because I hold the keys myself and I am not nearly as large a target as a bank. Is it better to go after one person’s money or one million people’s money?

I see SMS as a simple deanon rather than a 2FA.

Forget about biometrics, they are way too insecure.
Our cameras have reached a stage where we can replicate fingerprints from photos. ‘What you are’ is useless when we leave part of us everywhere. And furthermore, in parts of the world, authorities can force you to unlock your device with biometrics but not with passwords.

Biometrics can be fine when they are layered on top of other authentication methods.
IphtashuFitz@lemmy.world 9 months ago
Exactly. See my reply in another thread where I describe a “person trap” that I used to go through to get into a secure facility. Its biometric check analyzed the geometry of your entire hand. It wasn’t just a fingerprint scanner.

I strongly disagree. That’s like using MD5 and saying ‘It’s OK, we use SHA256 down the line’. Information encrypted with it might as well be in plain text.
frezik@midwest.social 9 months ago
That’s not how that works. If you were using MD5 and then immediately SHA256 the output and not using it for anything else, that would be fine. You’re not accomplishing much in this specific case, but it’d be fine.
When you layer security, the attacker has to pull back each layer. You don’t rely on any singular layer. If the attacker needs biometrics AND a code AND a physical key, that’s very good security.

For many people it works well as a trade-off between security and convenience. It may not be for everyone though and that’s okay. Nothing stops you from using a password/passcode to secure your passkey instead.
