I don't like passkeys

    Passkeys have a marketing problem where no one is able to describe simply what it is without having to use technical jargon. There's also the problem where each OS tries too hard in pushing this to the face of end-user

      Imagine a password, but it a) types itself for you and b) detects when it's being sent to an impostor site and blocks them from seeing itself, so it can't be phished.

      Tada, passkeys.

        Cool, where are they stored? (I know the answer: 'it depends', and that's the big problem with their usability: most users haven't a clue what the answer is and most tech support can't answer that question straightforwardly because it depends on some decisions the user probably didn't even realise they made).

          On my keychain in a USB hardware token. With a couple of backup tokens in fire safes.

            If you're using a USB hardware token your knowledge of it is at least an order of magnitude better than the median user's. I know where my passkeys are stored, I don't know where my family member's passkeys are stored and neither do they. The same is true for most of my otherwise fairly technical co-workers.

                Absolutely not. If that is required, I will do my damndest to only use implementations that deliberately lie about the hardware status. Your line of reasoning is dangerous.

              Then that family member does not worry like you do worry. The main point is assuming one can have a proper security for Google account - everything else becomes easy.

              The fearmongering of losing google account should stop. Yes, some people lose it. There are a larger proportion losing/getting pwned by repeat use. For the majority - just pressing the fingerprint to access an account (like amazon/eBay) via passkey is great.

              Fairly technical co-workers - I used to suggest them to buy USB security key few years ago. Now that same fairly technical some how has at least 2 devices with them - so they just skipped the USB security key need - and just use Google (in Android) or iPhone in Apple ecosystem. Everything just works.

              Yes, there will be a poor soul that may lost everything with only one device.

                People keep their entire lives in cloud accounts these days. Their passwords, financial history, copies of important documents, baby photos, etc. Losing access to it is incredibly disruptive and may result in unrecoverable losses.

                It shouldn’t be this way, but it is.

                  At the same time, I know so many people believing DIY raspberrypi based NAS and losing lots of data (thankfully they had cloud backups).

                  Not everyone has access to server grade hardware.

                Until they lose access to that account and then it becomes my problem to solve.

                1. faust201 · · focus · HN ↗
                  This is a different issue. Not everyone has a data engineer - know it all as a family member.

                  And you need to accept it works for millions.

                  1. rcxdude · · focus · HN ↗
                    Working for millions doesn't imply a good hit rate.

                      My actual experience is people with passkey are fine. No more account take over. Mote over they like frictionless login.

                      Yes there are few that used bitwarden and lost everything as their sync using syncthing failed.

          2. UltraSane · · focus · HN ↗
            The biggest issue with passkeys is that since most USB tokens that support them don't allow syncing the private key to a backup device you have to enroll ALL of them to every site that supports passkeys. This is annoying but it makes storing backups in secure offsite locations impractical.

                The entire problem with passkeys is that zero of the issues should have been a surprise, because it should have been part of the design discussion from the start, so the fact that it's not properly implemented before being forced on users says that either it's been done horrifically incompetently and nobody should trust it, or they internally found these concerns and ignored them which means this system is not at all meant to help us, so why is it being forced on us?

              It's beyond annoying. It's creating needless toil that no "normies" will ever actually do.

              I'd love a hardware sold in multi-packs and "born" at the factory with identical internal device key encryption keys (DKEK). I'd love, even more, if a token just allowed you to "commission" new ones w/ a user-specified DKEK on first use.

              I'd use one token as a daily driver and store the other(s) in safe location(s), empty of my personal key material. (Or, if I can just commission a new token w/ my DKEK, store a printed copy of my DKEK in a safe location.)

              Give the token a mechanism to "type" a backup of its internal state, encrypted with the DKEK, as a USB HID keyboard. That gives me an easy way to backup the token each time I enroll a new website.

              If I lose my daily-driver token I just pull a spare from storage, import my last backup, and I'm up and running.

              That would kick ass. No "You just need to buy two tokens and enroll them in every website" bullshit.

                  I haven't used a FIDO2 token other than playing around with it on a Yubikey. There, at least, I have to have the PIN to unlock the Yubikey before I can use the FIDO2 credentials (if I'm remembering correctly).

                  Are there hardware token implementations where mere possession of the token is all that's necessary to use the passkeys stored on it? That's incredibly stupid, and should have been disallowed by the standard, if that's the case.

                      I didn't realize PIN was optional.

                      See my other comment re: the IT industry being fools.

                    That is how almost all standard FIDO2 tokens work. You just have to press the capacitive sensor when prompted. You can get fancier biometric tokens that require a fingerprint.

                      That's the stupidest thing ever.

                      All this hullabaloo taking away user freedom to export keys and backup tokens but physical possession is all that's necessary to use it by default.

                      We are a ship of fools, the IT industry.
