Comment on Big Tech passkey implementations are a trap | Proton
paraphrand@lemmy.world 7 months agoIf you think forcing everyone to carry an object other than their phone around so they can use 2factor with it when they already have their phone so they can use it for 2factor with other things you are delusional. Or if you said I need to go to my laptop when I’m logging in on my phone and vise versa… that’s nonsense too.
Authy on my phone is just as “dumb” as Keychain on my phone.
How else are you imagining this should work that you could get normal people to do?
For Apple, it’s your iCloud account that everything depends on, and it’s the weakest point. Not by itself maybe, but in practice there needs to be a way to reset your iCloud password, even without your phone. Currently I believe that’s just an Apple representative asking life questions, but that information is mostly publicly available. There needs to be a better way.
A physical 2fa device may be just what we need to securely rest our iCloud passwords, keeping everything else more secure
If I’m on my laptop, and the 2fa code shows on that same laptop, it defeats the purpose of it. The point is sortation of security privileges, ask this just adds more work while providing no less security to the device. It does protect you from remote compromise, though.

I bring my yubikey with me, it’s in my keychain. This is not only more secure against phone theft/access, which probably is not very relevant for most people, but it spreads the risk of locking yourself out.
For example, I was in Iceland with my girlfriend and she “lost” her phone. We wanted to locate it, so I logged to Google for her, which asked 2FA. If she used her phone, she would have been toast. Instead I made her use yubikeys too, and she just logged in and found her phone.
Obviously you can lose your hardware tokens too, but it’s generally less likely (you take out your home keys way less than your phone, for example). You can also backup your TOTP on multiple devices etc., of course.
