- YES. This exactly. I work across multiple devices, some of which are nonstandard/uncommon (Linux, Xiaomi China ROM, ...) and I've NEVER had passkeys work properly - yet everything constantly prompts me to add one. Even if they did work, I'd have to carry around hardware keys or register each computer separately. And the lack of backups if a device is lost/broken is definitely a larger concern for me than being phished of my TOTP keys.by Liftyee
- I continue to avoid passkeys but it's becoming an incredibly dense minefield. Certain sites try to trick me into adding one each time I log in and I have to be careful to dismiss the 1Password prompt, then dismiss the chrome prompt, then dismiss the OS-level prompt (all back-to-back). It's so incredibly user-hostile.by joshstrange
- I try to boycott passkeys due to built-in attestation feature in the standard. Not active now, but given how Google+Apple already use the passkey feature to lock you into their ecosystems, it is just a matter of time until their service will require that the passkey is attested from a non-rooted Google or Apple device. I think this will especially be true for Google to prevent AI scraping bots. Turning this on does not require anything, once passkeys are widely used, Apple, Google and Co. simply can flip a switch.
- I respectfully disagree with the author!
Passkeys have been a massive quality-of-life improvement. Yes, there's the minimal risk of lockout if you lose access to the passkey (though almost every site I've used that implements pk's lays it on top of their traditional user/pass auth flow), but generally speaking most people use iCloud or their Google account to store their passkeys, and because those sync everywhere, this isn't a real risk.
I love not needing to deal with 1Password's autofill being flakey and having to CMD-C/CMD-V passwords/passphrases/OTPs on these sites.
I like Yubikeys as well but they are super inconvenient by comparison when dealing with multiple devices. Setting them up is also very user-unfriendly in general; doubly so compared to passkeys.
Now, what I'd REALLY F'IN LOVE to see go away is the passwordless/magic link auth flow wherein you authenticate by clicking a magic link that gets sent to your email or text message inbox.
"Emails are super easy to hack and we're still not sure whether text messages are safe to send on US carriers, so let's have everyone click on a link sent by email or text so that they don't have to deal with those pesky passwords that iOS or Android will automatically suggest for them." Like, what?
by nunez - Very solid points, and I love the focus on the fact that passkeys are addressing threats irrelevant to regular people, while ignoring those that matter. But I think it's still incomplete, because it's missing the biggest blind spot in design:
Password sharing is a feature, not a bug.
Security industry failed to implement the most basic feature one does with access control at individual level, which is delegation of authority. Physical security in form of "bearer" devices, such as keys, credit/debit cards, transit tickets (except those newfangled ones bound to photo ID), etc. all support this by default.
Ad-hoc delegation of authority is a normal thing to do, something we do all the time without thinking. Asking your kid or friend to do groceries for you? You hand them your debit card and give the PIN. Need a nanny to walk your kid from school and stay with them until you're back? You make them a copy of your house keys.
This carried over naturally to technology realm. A colleague needs to get some data that happens to exist only on your machine, while you're away? In normal non-corporate places, you just write the password on a post-it and give it to them, or put it in a drawer and tell them to go look there.
Security industry failed to provide a reasonable alternative path for over four decades now, and instead continues to deny the very existence of the need for ad-hoc delegation of authority. Passkeys are a bad choice for regular users largely because they're designed to prevent delegation - on top of the other issue, that the author correctly recognized, which is that by far the biggest threat to regular user is that of loss of access to account.
by TeMPOraL - While the technology itself may be great (I don't really know since I don't use them) it has been co-opted by the tech conglomerates as another form of isolating and walling off users into their ecosystems.
And honestly, nowadays, if tech companies are pushing really hard for something then that is an immediate red flag for me and it bears more scrutiny. One of those "if you see them running that way you run the opposite way".
by elteto - The point about poor support for 3rd party managers is so frustrating. Because this is correct, that is the obvious solution for the normal user, but passkey implementations somehow do not know how to deal with it.
Amazon prompts me to create a passkey everytime I log in, even when I logged in with a passkey, because my passkeys live in Bitwarden rather than my OS or browser.
And the confusing mechanism hurts there too: I'm always a little bit afraid that i'm somehow more in danger because I keep them in a vault that's shared on all my devices rather than a TPM, because whenever the protocol is explained the "it can't leave your device" part is highlighted as the main source of the security, except.... mine obviously do leave my device, with the vault, so.....
- Passkeys do marginally improve security against MITM and phishing attacks, but they are primarily for protecting the lowest common denominator from themselves: people who re-use passwords and/or don't use a password manager.
If you use multiple devices throughout the day, registering passkeys in all of these systems becomes a big headache with O(m*n) complexity, so putting the passkeys in a password manager is the only realistic solution. But this still breaks the login flow for a very common use case: how do I log in on a device that I don't own? With a password in a password manager I at least have the option of manually typing the password.
The biggest problem, though, is how users are pushed into it without any warning or knowledge of what they're signing up for. I've accidentally set up passkeys just by clicking an okay button a few times in the past and had to go back and figure out how to undo it after being blocked from login on another computer (which computer was I on again?).
