I do not know how to use a Passkey in a way that won’t impede how I log in to systems. I’ve been in tech for 26 years, and I understand the Public/private key behind what a Passkey is. Here’s what I don’t understand: I access a website through at least four different devices (my iPad, iPhone, Windows Desktop computer, and MacBook Pro) and three different browsers on each device (Brave, Firefox, Safari) , and I use La…

> Edit: One final consideration, my spouse and I share user/name passwords for some things (notably Pandora and our Amazon Prime account) since they don’t handle things like family logins well; how do both my wife and I use amazon or Pandora with passkeys? Do we each set up passkeys? How do I get her Pass if that’s not an option? Lets say it is a android phone. Open amazon app. login in the usual user/password + 2FA…

Thanks. One glaring issue I see is that right now police can’t ask you for your password in the USA (a violation of the right against self-incrimination). They can however get a search warrant for your device and your biometrics, and wouldn’t need your password if they can gain access through your pass key.

It’s quite the opposite. Passkeys are phenomenal for a lot of consumers. Based on this thread, it’s the engineers who understand authentication in the first place and have their own system (eg password manager) that are confused. Consider a user in the Apple ecosystem: you are already conditioned to just do Touch ID or Face ID when asked. I was on Amazon the other day, it prompted randomly for “want to set up a passk…

A password manager let's me use my service specific credential from any device, securely and decentralized. Passkeys lock into a specific device and seem easy until you need to use another device. But instead of being a credential you own and control, across what could even be a local password manager, it's one password to everything. Maybe it is more secure than a regular password in some cases but it largely seems…

1password and KeypassXC both support passkey syncing across devices and operating systems.

Is "passkey" only supposed to mean devices that implement specifically U2F, WebAuthn, etc.? I would have thought TOTP and challenge-response hardware tokens to count, including cellphones with apps that implement such. As to > No major bank revokes your password when you setup a passkey, either. If we're talking about requiring 2FA via TOTP or challenge-response hardware tokens or banking apps implementing such, that…

> I would have thought TOTP and challenge-response hardware tokens to count Those are absolutely not passkeys. Passkeys are just WebAuthn (from what i can tell).

Such a generic word. I imagine there are tons of CLI utilities out there with a --passkey option that refer to simply files with a key inside. Kind of crazy that it's being used to mean specifically devices that implement a specific protocol.

Kind of feels like "crypto is a type of currency and not all cryptography", or "SQL Server is a specific product of Microsoft".

Wonder if how it happened this time was people read the specs and explanations of WebAuthn, saw "passkey", never seen that word before and assumed it's only ever been used in the super narrow context of WebAuthn so it can only mean that. Maybe "header" can only ever mean "HTTP header".

Thinking about it like that, it may be more like how "latte" is specifically espresso with milk (it's really just milk), or "queso" is specifically cheese dip (it's really just cheese of any kind), or "masa" is specifically made of corn (it's really just dough of any kind, or it's mass like atomic mass is masa atómica).

The first time I got asked by a site if I wanted to use a passkey I immediately googled what they were and... never really found the answer, not in the 5mins I devoted to being distracting from my task at hand anyway.

100% had said something to the tune of this months ago in another thread on passkeys

> Passkeys need a marketing campaign and UX overhaul. I’m a technical guy, but I really don’t understand what the fuck is going on when I use a passkey. All I know is one day it appeared as an option and it let me login to things. I don’t really understand where it lives, what device it’s tied to, how scanning a QR code on Google Chrome on my phone magically logs me in, etc etc.

The user was not educated on this. Hacker News is the top 1% of computer power users. You gotta understand to someone’s grandma or mom or brother who works in real estate none of this makes any sense nor will they educate themselves on what it is.

> It seems like everyone wants to be _the_ password manager for all your passkeys. Which defeats part of the point of passkeys in the first place in that they are supposed to be device-bound, the private key held in the TPM or secure enclave or whatever other security chip, mathematically non-exportable. Storing all your private keys in a cloud vault still leaves you exposed to potential credential theft if your vaul…

> Every device is supposed to have its own unique private key, stored in TPM, released only when passing the user challenge (biometrics or pin, or a yubikey). This is a misconception. A particular service can choose to enforce those class of passkeys, but most don't need that and shouldn't. Passkeys are primarily meant to replace passwords and be hard (but not necessarily impossible) to exfiltrate. The key difference…

Passkeys is basically a brand name for "discoverable credentials" (a Webauthn term). They do a little more than that technically, but in practice their purpose is what you said. Replace passwords. Or more accurately usernames and password pairs. This is in contrast from 2FA, but even before Apple started marketing Passkeys the FIDO standard supported the concept of Passwordless authentication, alongside 2FA.

Passkeys came together with multi-device syncing when Apple introduced them and IIRC it was pushed as their killer feature by Apple back then, but passkeys can also be completely device-bound. The marketing around this was all quite confusing, but it's a bit too late to fix now.

What we got, as far as the average consumer should be concerned, is that "passkey" is any authentication mechanism (not the actual credential) that can replace a password. And it's still confusing.

This is much, much simpler than you think it is. Passkeys are just passwords that require a password manager. If you lose your passkey, you'll reset your passkey the same way you reset your password, probably with a "forgot my password" email. (But you're not going to lose it, because you use a password manager, and the passkey will be stored there and synchronized to all of your other devices.) The weird part is tha…

I am an engineer and have some insights on the discussions and developments around it. ITS NOT SIMPLE AT ALL 1.

There are some parts of this that are correct and other parts that are incorrect:

>1. The idea was to provide a phishing resistant authentication method for enterprise users (companies loose quite a lot of money to phishing).

This is incorrect. The idea was to provide a phishing resistant primary factor that could compete with the usability of passwords to the point that consumers would actually want to adopt it.

>2. Majority of industry players shared the vision of a credential which is available across the platforms and browsers

This is correct/accurate.

> 3. The vision for collaboration never materialized so everyone went their own way to implement it. Examples would be google rolling out browser (Chrome) managed authentication which led to this situation where even on the same machine you have to remember which browser you used to create the Passkey credential.

IIRC at least Chrome's default on Apple platforms is to save to the Passwords app by default. There are then multiple fallback options in the case that the user isn't using the default credential provider -- ultimately falling back all the way to cross-device passkey sign-in (the QR-code initiated sign in) or Security Key.

The security engineering behind the QR-code cross-device sign-in stuff is interesting: https://www.corbado.com/blog/webauthn-passkey-qr-code#4-pass...

That said, I strongly agree that fragmentation of where passkeys get saved is super confusing and I wish there:

(a) was stronger guidance from the FIDO alliance on both educating users that it's totally fine to have multiple passkeys across different ecosystems (e.g. one in Apple, one in Google), and;

(b) that all the credential managers could figure out a better way to place nice together and make it super clear to the end-user where a passkey is getting stored, what context it's for (e.g. personal vs. work), and actively help them store it in the right place (which might be different credential manager app for personal vs. work!).

> 4. Interestingly enough the earlier popular name was WebAuthn, Apple started calling it Passkey on fly, given Apple's popularity everyone just caved in.

This is incorrect -- passkeys are not just another name for WebAuthn. If you go back and look at the original definition Apple gave for the word passkey, you'll find that it was meant to be a discoverable WebAuthn credential that syncs across a user's devices with end-to-end encryption. There was a bunch of industry thrash around the definition, but it seems like the original Apple definition has largely stuck/settled now, and when passkeys don't sync they're typically called "device-bound passkeys" rather than just "passkeys".

>5. My personal interpretation is that in some sense Apple wanted to be the default password manager on Apple devices.

If you go back and watch the original passkeys announcement from Apple, their stated goal was to create something that is both a better user experience and more secure than passwords. By "better user experience", they meant the act of creating credentials and then repeatedly using those credentials (logging in).

Part of actually achieving that goal means there needs to be something that "just works automatically out of the box" which means there needs to be a built-in credential manager. That said, Apple credential manager had already existed for many many years by the time passkeys came around. The only thing that changed was instead of being solely accessible from inside System Settings (which was hard for the average user to find), the functionality moved into a standalone Passwords app.

>6. This is when all password manager companies jumped in strongly to save their business and the protocol went into a direction where you can use your existing password manager to store the credential/Passkey as well

I think it's a huge positive that all the password managers jumped on board, and that they could jump on board (since WebAuthn is an open standard). I think this is a good thing for consumer choice and for overall adoption and perception of passkeys. A lot of folks (including on this thread) have big tech lock-in conspiracy theories about passkeys, and the conspiracy theories would be even more prevalent without a wide spectrum of consumer choice for credential managers.

>If you are using it with security in mind then my recommendation would be to use a hardware backed security key with NFC enabled. Everything else is pretty much lipstick on pig, they are worse than passwords in some sense from usage perspective.

Passkeys protect against phishing attacks, and you get that protection regardless of whether the credential is hardware-bound or not. That protection comes from the cryptographic binding of the credential to the domain at the time of credential creation.

The only additional protection you get by making the passkey hardware-bound is preventing an attacker who has already compromised your operating system from stealing the credential. But! Unless you are also doing hardware binding of the session (aka cookie) after sign-in, then doing hardware binding of your credential is mostly security theater, because the attacker can just wait for you to sign in and then steal your session.

And there is standards work happening separately for hardening session security, such as DBSC: https://w3c.github.io/webappsec-dbsc/

You can use both hardware bound passkeys (where you may not even be able to read the secret so you probably would want to add multiple device passkeys to a site) or shared passkeys (where the private key can be synced through something like a cloud service across your devices, see Bitwarden, iCloud)

> hardware based

Sounds good until you realise theres no way to transfer/back them up and you are limited to 100 [1] (previously 25?).

Personally my password manager has almost 4x the entries so hardware passkey solutions are a joke leaving users with single option - upload their keychains to ms/apple/etc clouds where they can be requested by any gov under the sun for x reasons.

I find Google Password Manager makes passkeys pretty easy to use. As long as you don't accidentally create a passkey some other way. Hopefully websites will adapt to the reality of how people use passkeys in practice and some of the UX weirdness around them will disappear over time. One annoying thing though is that while they recently added password sharing, they don't allow sharing passkeys. Basic passkey sharing w…

Considering Google's track record of locking people out of their accounts it'd be very risky to trust them with your password manager.
