Passkeys are built on the FIDO2 standard (CTAP2 + WebAuthn standards). They remove the shared secret, stop phishing at the source, and make credential-stuffing useless.
But adoption is still low, and interoperability between Apple, Google, and Microsoft isn’t seamless.
I broke down how passkeys work, their strengths, and what’s still missing
While the lock-in issue is annoying and a good reason not to adopt these, the device failure issue is a tech killer. Especially when I can use a password manager. This means I can remember two passwords (email and password manager), make them secure, and then always recover all my accounts.
Passkeys are a technology that were surpassed 10 years before their introduction and I believe the only reason they are being pushed is because security people think they are cool and tech companies would be delighted to lock you into their system.
Cops also love them because they make getting access to your entire phone including all accounts simple as cake if you use fingerprint/faceID to unlock your device.
Password managers store passkeys. They’re portable and not device-locked. Been using them on Bitwarden for like 2 years now.
You can store Passkeys in open source password managers.
I don’t know most of my passwords, so the step to passkeys doesn’t feel like a big one. I also really like the flow of pressing Login; Bitwarden pops up a prompt without me initiating it; I press confirm. Done, logged in, and arguably more secure due to the surrounding phishing and shared secrets benefits.
Sure, they probably work great when you have your *passkey manager on the device, but that’s not when I need to have backup routes into my accounts. When using a new device, or someone else’s, having even a complicated password that can be typed or copied-pasted has way more functionality.
As far a I can tell, using passkeys would only risk locking me out of my accounts. Everyone else is already effectively locked out.
I can access my password manager via the browser from any device.
Can’t you access your password manager from a web browser? Or your phone?
Oops, meant passkey manager, fixed it.
This is the only accurate take in the whole thread.
Passkeys solve “well, can’t be fished” by introducing 2 new problems and never resolving super prevalent session hijacking. Even as a basic cost-benefit analysis, it’s a net loss to literally everyone.
I came to sorta say this. Regardless of the system if it can fail and if people have to recover an account then phishing will always be a thing. In person options to deal with an account like with bank branches or government offices are the only true way of making things more secure. I sometimes think it would make sense for this. One rare thing I have seen that gives me a bit of hope is the use of in person at the post office for us government accounts. Thats exactly how it should be done. Secretary of state for state and usps for federal. They are the only agencies with enough physical locations.
I think they are being pushed because cool technology on paper. Whenever I read an article about them, I can’t help but think about the human factors. How are passkeys created, often by a password or email. okay… that looks a lot like a password. Oh you lost the passkey, here lets send you one again. It stinks of a second factor without a first. Sure, the passkey itself is hard to compromise, but how about its creation. If your email is compromised I see no difference from passwords or passkeys.
They don’t email you a passkey, what are you even talking about?
The flow I hear about when people talk about passkeys is sign up with email. Code gets sent to email. Code is entered, passkey gets generated. There always seems to be some similar step that looks like that, and often you have new device or reset that looks the same. Sure the passkey itself is secure, but how do you get it, how do you generate it, how do you validate the first time?
None of that is remotely true lol. You don’t get a passkey, you generate. Nothing is “sent” to you at any point in time, it has nothing to do with email.
Question is by what? I could see an argument that it is an overcomplication of some ill-defined application of x509 certificates or ssh user keys, but roughly they all are comparable fundamental technologies.
The biggest gripe to me is that they are too fussy about when they are allowed and how they are stored rather than leaving it up to the user. You want to use a passkey to a site that you manually trusted? Tough, not allowed. You want to use against an IP address, even if that IP address has a valid certificate? Tough, not allowed.
They were surpassed by password managers and 2fa.
Technically they are the 2fa. The second factor is something you have. I store all my passkeys in my password manager too, so I’m not faulting you, but technically that’s just undoing the second factor, because now my two factors are “two things that are both unlocked by the same one thing I know”. Which is one complicated factor spread across two form fields.
Password managers are a workaround, and broadly speaking the general system is still weak because password managers have relatively low adoption and plenty of people are walking around with poorly managed credentials. Also doesn’t do anything to mitigate a phishing attack, should the user get fooled they will leak a password they care about.
2FA is broad, but I’m wagering you specifically mean TOTP, numbers that change based on a shared secret. Problems there are: -Transcribing the code is a pain -Password managers mitigate that, but the most commonly ‘default’ password managers (e.g. built into the browser) do nothing for them -Still susceptible to phishing, albeit on a shorter time scale
Pub/priv key based tech is the right approach, but passkey does wrap it up with some obnoxious stuff.
Even if you are really careful, your details can always be leaked from a company server during a breach. If the companies adopt passkeys, that issue isn’t there. Because there isn’t a password anyone can randomly use. That’s why I feel big tech companies are moving towards it.
I’ve found a pretty good use for a passkey. Docusign. About every 3 months I need to docusign something at work. The process involves logging in, changing your password, logging in again, opening the document, logging in to sign, logging in to finish. The only steps you get to skip if there’s more than one document is the initial log on, and changing password. So with a passkey I just touch it a bunch of times and there’s no password change.
Sounds like a password manager would make that way easier. Changing your password would involve a few extra clicks. Also, you might want to check with your IT folks. Asking people to constantly change their password is a good way to weaken password strength. I don’t use docusign, but there is probably a setting that they can change.
Oh, I agree, but I have to argue enough with professionals who know better as it is. I have to do it every day with recent PhDs as a BA who’s been doing the job for 15 years. At this point it’s not my problem if something happens. I have other things that affect me every day to fight about. I’ll just continue cycling through my no repeats after 10 changes, 12 character passwords and using my yubikey for docusign for my own sanity.
sounds like a better solution is don’t use docusign
K, I’ll go tell the CEO that they need to come up with something different.
There’s like a million other free/libre digital document signing platforms out there. Try one that doesn’t suck.
Unfortunately, per the comment you replied to, that isnt under my control.
