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 LastPass. If I accidentally set up a passkey on my phone (let’s say I use Safari one day instead of my go-to, Brave), can I still log in without that passkey on other devices? Is there a way to ensure that passkey can be used on other devices? Can I add another passkey on another device? How many passkeys can I set up for a particular site/app? I have at least 6 different combination of browser/devices in use.

I don’t want to use Passkeys because I don’t the answers to those questions, and I don’t know whether each website/app that has set up Passkeys has decided the answers to those questions in the same way as the others. For now, I’m going to stick with LastPass and use Passwords; because no matter whether I lose my device or not or whether I’m on my own devices or not, I can be sure I’ll be able to get into a site/app.

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?

A potentially good idea got corrupted by vendors, password managers, browsers, etc trying to assert control. I'm also an engineer and I find the UI around passkeys entirely unclear, but it doesn't have to be that way. It seems like everyone wants to be _the_ password manager for all your passkeys. They don't want to make it easy to understand that is what they are doing though, they just happily offer to "handle it for you".

My non-technical friends are extremely confused by passkeys and if they should use them and how to use them and I honestly don't have very good answers. It is a mess. I don't believe an inherit mess, but one created by the companies and projects trying to take advantage of the new system.

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 that password managers provide no way for you to copy and paste your passkeys. To present a passkey, you have to use a password manager. This makes it impossible to copy and paste your passkey to the wrong person (someone trying to trick you).

Major password managers don’t even allow you to export your passkeys to a file that you can read/backup yourself. Instead, the password managers each have their own finicky app-to-app mechanism for transferring passkeys from one password manager to another. (I think all the password managers kinda like that lock in.)

Finally, note that for logging into your password manager itself, you'll always require something outside your password manager to login, probably a password, but possibly a YubiKey; your choice. (It's your one "last password," as they call it.)

https://danfabulich.medium.com/passkeys-are-just-passwords-t...

P.S. It's past time to move off of LastPass. LastPass lost all of your passwords again last month, just like they did in 2022. The most similar service is 1Password. If you like LastPass, you'll like 1Password about the same, but 1Password hasn't had multiple terrible security breaches.

This is the main reason I've avoided passkeys. I have these exact questions and there's no a clear explanation given for these. I don't want to lose access to important accounts.
In practice, because site owners know users are going to mess up having their passkeys on all devices, I've not seen any insist that a passkey _must_ be used, and you can always log in with your password (or worst case, email magic links) as a fallback.

However, this negates the primary stated objective of passkeys, removing the possibility of users being phished, so I'm not sure how long that will remain the case everywhere.

I've also encountered sites that have a login with passkey prompt that then turns around and asks for TOTP 2FA or email confirmation anyway, which to me seems to negate the primary customer benefit of passkeys...

Same here, also what if I lose the device?

I can safely write down a password on a piece of paper and keep it somewhere phyisically safe.

Passkeys and 2FA are a usability nightmare if you need to recover, or all the security vanishes if you put usable recovery mechanisms for the passkey or the second factor.

My issue is that they're touted to the consumer as secure, and they're not really doing much more than a complex password.

How do you generate a new key if you need one? Same process as a password reset. Does it prevent session stealers? Not at all.

Its "benefit" is grandma can't read it to an attacker. OK, well can grandma click a link and have a session stealer bork her life instead? Yeah, and attackers know that and just shift methods. Session stealing isn't a sophisticated attack, and so all that's being done is shaving a cost on PW resets in the interest of shareholder value, at the cost of security theater and locking up your keys in a single domain that holds control over our access to everything.

Listening to Yubikey and OnePassword talk about this, they actually say "One Person, One Device". Which really speaks to their failure to understand their users.
I think the intended workflow is you login with your phone and that device is now the authority that allows other devices to issue their own passkeys.

In my opinion it's a bad plan, because it elevates certain devices to privileged status, if you lose your phone you are hosed.

Passkeys should be allowed to be synced between devices and stored on password managers in the cloud. I am making my own password manager for my personal use, but have not delved into passkeys.

I get your problem, i don't really accept it as valid. Passkeys were always supposed to be fungible. You have one in your iPhone, a different one on your desktop. A third in your significant other's phone. All stored in the hardware tpm equivalent.

You can have 7 passkeys. You can have 14.

The real failure of passkeys (emphasis on the s!) is that people think they must only have one.

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.

"magic fairy dust to login to apps." is the most accurate description I've seen.

Unlike a password or a TOTP token, I know how those work, I know its my responsibility to keep track of them. If my passkey is on my phone what happens if I lose my phone? Do I need a unique passkey per device? How do I rotate them? What if a device gets stolen?

I'm so glad I'm not alone in thinking these are so poorly explained.

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 passkey to sign in easier”? I set it up and now I can easily sign in to Amazon on my mac or iphone with zero friction.

For the normal consumer this is not a replacement for “dig out my password manager and copy-paste/autofill my password”, it’s a replacement for “oh it’s prompting for my password again” -> proceed to type your shared password for all sites.

Like some folks already commented here, even as someone who has been working in tech for 20+ years, I find Passkey confusing. I understand the key aspect in computer science term, but I don't know how to use it across devices. Another big worry is that if I tie that to a physical key, then I might lose it (because it's physical) and never get it back.
FWIW: I find passkeys to be a very simple and easy to use concept.

Simple: it's like a password that I don't have to type in

Easy to use: because I use 1Password and just have it installed on everything. On Android, it can be set as the default passkey provider so, even on mobile, I am using passkeys shared across devices.

Is this "less secure" because I'm sharing the keys through 1Password. I suppose, at some level. But before that, I was simply sharing passwords through 1Password in the exact same way. So, I don't think my security posture has changed any.

What has changed is the UX and IMO for the better. Now I don't have to generate/fill/copy-paste text strings for user names or passwords. 1Password knows what site I'm on and usually responds automatically when I'm in a passkey context. If I have more than one passkey available, because I have multiple accounts (for something like Google Workspace), it shows me options and I pick the one I want.

Honestly, it's mostly a "just works" system and I like it a lot better than passwords.

YMMV, of course.

With physical U2F key, I could explain to my 78 year-old-parents "this is a physical key needed to access your account. Think of it like the front door key to your house. Don't lose it or lend it to anyone. We should have a couple of backup keys too." And they got completely understood and added it to all of their accounts. This was not hard. People assumed consumers were too stupid to do this without even giving them a chance.
The website for my HSA required me to set up a passkey last time I logged in. I set it up on my work laptop and my work password manager, which means I can now no longer access my account from my personal computer. This is fantastic, just what I wanted
It seems to me like those who like passkeys/consider them simple are those who entrust all their credentials to proprietary cloud software vendors that sync them to all their devices.

Those of us who are not comfortable with that and want to keep our credentials offline and sync/backup them ourselves have questions about how the registration/backup/sharing flows work exactly.

I see this as part of a trend together with remote attestation, age verification, CSAM scanning, restricting sideloading, etc that will lead to most interactions over the internet only being allowed if big tech and/or government can verify the participants, the contents, and the hardware and software used.

Even among techies, many support these developments, so it is just a matter of time before we have no choice but to join the former group.

UX is not the problem with Passkeys. Passkeys were designed to align with the interests of BigTech, who are bent on stopping the abomination that is general computing devices in the hands of consumers and forcing them into their walled gardens. The language that is used for taking away freedoms is the same as always, safety. Where we ended up with Passkeys is an operating model that is suitable for corporate devices, i.e. the user can only do what the owners of the device allow them to. Suboptimal UX is downstream from that problem.
I think portability is very confusing: they rolled out passkeys with no device portability (device-bound) and only recently added it (CXP). So for anyone with multiple devices it was a relative disaster - why should my Windows PC hold a device-bound passkey to anything? How do I login on Linux or macOS? Picking a password manager to do portability also means another kind of lockin, though maybe you can live with that kind if you really trust the company. Even so, the password managers all seem to be competing to have relaxed security, so that vault and account passwords are the same, or you are asked to type your master password into a webpage - surely we didn't replace per-site passwords with this?
I mostly love passkeys to be honest even though I use multiple browsers across multiple devices and OSes (iOS, Chromebook, Linux, macOS, Xbox, etc). Bitwarden’s support is (finally) pretty good.

My problem is that I manage a lot of accounts for my family which makes passkeys a nightmare. If I’m out and a kid gets chucked into a login flow that happens to require a passkey, I can’t text a password and TOTP code to the adult with them. I know that’s terrible opsec but the reality is people share accounts and passkeys are designed to thwart that.

Throwing my hat in the ring, I think passkeys were also invented by engineers with zero understanding of the average developer: https://etodd.io/2026/04/06/passkeys-are-too-hard/
I think about this a lot when using our corporate SSO tool.

When I hit the button to log into Slack, there are like, 3 popups in succession - the last one ultimately asking for my fingerprint. Then when I give it, there is a flurry of web pages that get loaded and redirects that happen until finally Slack pops up again.

There isn't any realistic world in which I check each window to make sure everything is happening right and I am not being MitM'd.

I'm a fairly technical person, and I would be unable to perceive the difference between a really tight security environment and my computer being hijacked.

> I run a tech company and I have no idea what a passkey is and at this point I’m too afraid to ask

I thought I was the only one!

I keep seeing people working on Passkeys get real defensive when told they don't make sense to people.

I've worked in tech 12+ years and I _hate_ when a Passkey prompt comes up, its only ever slowed me down.

But the devs who work on them are quite rabid, and keep dismissing real criticism of their implementation.

Passkeys are just SSH keys in how they work. We've been doing this since the 90's. The only people that use SSH keys are the Linux savvy users and those who are forced to via an enterprise solution for vaulting.

The average person doesn't know anything about this stuff nor do they care. I also have yet to see a Passkey solution that didn't also have a password on it and a nice little box letting people choose to use the password instead of the passkey. They just added a new layer on top of all the old ones and created confusion. Now people use password and passkey interchangably in conversations and no one knows what they are talking about.

Yes, a bit of a mess. As the only practical way for most to use is with a password manager. So essentially, all your accounts still have a real password, just you enter that into your password manager app. So if your device is every compromised and someone has your master password then you are screwed.

And of course, passkeys on most all sites don't really improve security since someone can just choose to login with user/pass instead since presumably very few sites allow you to have just passkey.

Also if you use a password manager you may get locked into using that platform. Or ideally using a third party one but then having to pay a subscription, or using an open source option that is not ideal for the average person.

If one uses a passkey as intended and without a password manager and the site truly only supports logging in via your passkey, for all the touted benefits of passkeys, that would be a nightmare if a person loses access to their device, etc.

Passkeys are a nightmare for techies that want to understand and manage their stuff. They were optimized for people who neither can nor want to understand, they just press the button that the screen tells them to press and live inside someone's closed ecosystem.

For that use case, they work fine, and they create enormous lock-in, because now moving out of that ecosystem breaks everything. One might argue that that means they're perfectly engineered for what they are meant to do...

My take: (1) I've had passwords handled pretty well for a long time now: same password manager for something like 15 years; (2) companies are pushing pretty hard to get me to use passkeys instead.

From (2) I assume that the companies see benefits to themselves. I don't care about benefits to them. I don't see much in the way of benefits to me, so I'm not changing anything if I don't have to.

I'll admit to not having looked into passkeys all that much. Someday, I might. But for the time being, I don't see much point. I imagine that eventually I'll be more or less forced to deal with passkeys in at least some contexts. Will leave that for later.

For now, it's all a big "no thanks" from me.

I signed into my Playstation account on a new phone. It told me to make a passkey. Its safe. So i said ok.

Later I tried to sign into my Playstation account on my computer and I couldn't. It said I needed to use my passkey.

I went back on my phone and deleted my passkey.

FWIW, Nintendo seems to have nailed the concept of passkey. I can sign in anywhere. If I'm on a new device, i just use my email password and 2FA.

I dont know why so many vendors find the need to complicate this. A secure solution implemented poorly can potentially be worse than an insecure solution.

One more anecdote on that front — I worked the help desk at a medical school during college. The IT department had their fun password requirements (number, special character, blood of a virgin, change every month, etc). Every single person who came to the help desk had their password written down on a sticky note on their laptops. These were med students , doctors, staff... everyone.

At some point these admins have to ask themselves whether they're actually helping people be more secure or if you're just making them jump through hoops.

I find it difficult to explain how to use password manager to non-IT person. Whatever I say, they say it is not secure. No amount of explanation will change their mind. They prefer to keep their passwords in their physical note book hidden in the safe (yes, they open the safe etc each time they need to log in somewhere when they get logged out).

As someone with ADHD a passkey is something I can lose easily and I don't want my accounts to be tied to any specific device. What if I have to upgrade my laptop tomorrow because one I use got bricked? Sounds like an absolute nightmare.

Password on the other hand I can remember for dozens of services, each very long.

I use Apple based passkeys to log into everything I can now. I have given it virtually no thought since all my relevant accounts and rolled out support. My non-technical close friends and family (consumer brains) have also done the same. I imagine it is a different case for non-Apple device users, but in the Apple case, passkeys are zero friction and truly life-enhancing for anyone who logs into things
Passkeys are a vector for locking your logins to Big Tech ecosystems. They support device attestation, which means the service you are logging in to can require you to only use certain Passkey clients such as those provided by Google, Apple or Microsoft. The Passkey spec authors also maintain a list of "naughty clients"[1], which are clients that allow the user to manage their own data how they want. Services could choose to block those clients for "security reasons," justifying the decision to force you to use one of the Big Tech providers.

Until device attestation is removed or strongly curtailed in the spec, I suggest you do not create any Passkeys. Which sucks, because it's otherwise a pretty cool tech.

Passkeys are a political play aimed at bolstering government support. They’re the privacy sabotaging arm of Digital ID. They go hand in hand with “age” verification. It’s all the same play. Get your identity, get your access credentials, give it to the prying eyes.
This comment section is the best example of all time of the arrogance of Big Tech and its employees. Please try to take a second thinking outside of your bubble before commenting ridiculous stuff.

Yes, as a wealthy American, you "live in the Apple ecosystem". 99% of the world doesn't. And guess what, they're affected by passkeys all the same. They use a Windows laptop, and either an Android phone or iPhone. A lot of people even have an Android phone and an iPad. And no laptop at all. But at work or school they have to use Windows.

It's quite simple. Besides people "living in a single ecosystem" (discussed above, this is almost nobody), passkeys are only viable (i.e. not very painful to use) if you use a dedicated cross-platform password manager. Yet people who use those - which too is a globally negligible percentage - are exactly the people who tend to have near nothing to gain from passkeys, and only to lose. The majority of them is tech-savvy and they use auto-generated unique passwords. In that scenario, the minuscule improvement in security is meaningless and not worth it.

Ironically, this comment section shows exactly why passkeys are a shit show. Half the people here are exactly those who are coming up with this shit in their FAANG jobs, happily part of the global 1% (of which their tech-illiterate grandma too is part of), and they have no idea or care in the world for the remaining 99%. Unless of course this was simply a land grab for lock-in, which is about as likely.

I really don't get passkeys and how they are supposed to be safer.

Currently I save all login tuples to Bitwarden and store OTP secrets onto Aegis. Could have been 1password and authy, it's irrelevant. The thing is, I only get pwned if both are compromised.

Now with ubiquitous passkeys in Bitwarden if someone has access to my vault unencrypted it's already endgame.

Okay, I'm a tech nerd I admit it, but for my personal authentication life I find passkeys to make sense.

All my passwords and SSH key are already in Bitwarden. When a site starts supporting passkeys, I add that to Bitwarden as well. Now, instead of logging in by auto-filling my username and password, I just press the passkey login button (that hopefully exists) and click on the Bitwarden popup to select the account. It's less button presses for me, and I cannot be phished, nor can my passkeys be leaked on the dark web. All thanks to some fancy cryptography.

Okay, sure, if someone steals my Bitwarden vault by snatching my laptop while it's unlocked or something, I end up pretty screwed. That security aspect did not change, so I still use TOTP for all important services.

Also, I've made one invite-only web app where single-use invite codes and passkeys are the only ways to log in. It was not too hard, it was fun, actually. And I get the peace of mind that account sharing is pretty much impossible were a bad actor able to get their hands on an invite, as is hacking other people's accounts.

(Okay, I concede that I've had to help multiple people who find passkeys confusing as a result of this whimsical decision, and that it just might be that nobody is using my web app for real. So I'm just speaking from nerd privilege here... But it works well, trust me!!)

My biggest issues with Passkeys is how inconsistently they are implemented and how opaque they attempt to be.

I understand SSH keys, I've been using them for decades, I know where they live, I know how to secure them.

Passkeys are murky as fuck. Is your PW manager supported? Do they sync? Where are they stored? How can I move to another PW manager if I want to in the future? Can I have more than 1 passkey per site? And the list goes on.

I _know_ some of you out there can answer some/all of the questions above but it's mostly on a per-site basis. Passkeys take too much of the control out of my hands and I don't like that.

Even more than that, I hate how they are trying to be pushed on me at every turn. Login -> Want to save a passkey (but they never call it that, they use some other confusing euphemism)? I click "No" and then it proceeds to pop 1Password's UI, then I dismiss that and it opens Chrome's passkey save UI, I dismiss that, and then it opens the OS's passkey UI. It's incredibly disrespectful and unclear.

I never use anything but 1Password but somehow everyone (OS and Browser) try to reach their grubby hands in. This is what scares me, I don't like having to be on high-alert to not accidentally save a passkey in Chrome or Safari and not realize until I'm on a different device and notice it's not in 1Password.

Lastly I trust the developers implementing passkeys... none, I trust them none, zero, zilch. I don't trust them to pick the right defaults, I don't trust their recovery options, and I know they will always pick the configuration that benefits them and not me.

No, for now I'll stick with my as-long-as-you-let-me-make-my-password random passwords which I never copy/paste into random website and be perfectly safe, thank you.

Passkeys bother me because they depend on the availability of another device. That just won't cut it for a lot of folks, especially people that are prone to losing devices. It's also annoying to have to deal with the 50,000 places that are fighting to keep your passkeys, leading to fragmentation and uncertainty as to where these credentials are stored.

Haphazardly implementing passkeys also has big problems - one vendor I use implemented them rather badly and randomly one day, completely removing the previously-solid password/MFA setup they had, replacing it with a "you are required to confirm on your phone with no other alternative" passkey, which was really annoying. I don't like my logins messed with. Passwords/MFA, while not perfect, work very well for most people, myself included. Passkeys still feel like they are in a very immature state.

I think the problem was that there wasn't a "Best Practices" way of using them when they were launched, which really prevented describing them in a consumer-friendly way.

And web site implementors couldn't follow that golden path, or describe the golden path, so there's fragmentation in usage and meanings and practices, making it far more confusing.

I love passkeys, I want to eliminate any and all password-based logins and switch entirely to passkeys. It's such a better experience, it's a "physical" key that can be backed up to multiple devices, and thinking of it like a key for a physical lock really gets at the core of its capabilities. But locks can be used in many many ways! Maybe you need to open the lock and still tell the guard a password, which is weird, but how most websites still operate.

Reminds me of Yishan Wong's description of OpenID's failure:

https://www.quora.com/What%E2%80%99s-wrong-with-OpenID-Why-h...

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 would be nice, but it also seems possible to implement fancy sharing features that wouldn't be possible with password sharing. Things like sharing one time use passkeys or time limited passkeys or limited access passkeys or secure revocation of shared passkeys. I hope people are thinking about this.

I used to think this but once you treat them as another path to get in they become really useful.

Yes, you still have your 2fa and password, but you create a fast path in addition to it when you get in.

It became even more useful once I stopped insisting they have to go into 1password

The cumbersome and poorly designed workflows surrounding passkeys are a significant hindrance to their adoption as well. It surprised me how bad they were when they emerged -- it was as if the UX was intentionally designed to kill passkey adoption.
Passkeys were invented so hacked sites could brush off their leaks with "no credentials were leaked" and minimise any regulatory fines. This is the reason why its being pushed by the big players.

Additionally this puts the same players in control of your logins - want to sync your passkeys? - enable "iCloud Keychain", or some other 'trust me bro' app that will 'securely store/sync your data' - no thank you.

In perfect world users should be able to generate a certificate, upload it to a couple nfc capable ubikey like devices that blow a fuse afterwards preventing from additional writes/reads and use that to login to every app ever. You would buy such devices in packs of 3, upload same cert to all, hide the other, burry the third.

My Health savings account provider is trying to force the use of passkeys. I assumed it was a cynical attempt to force the use of their app, which I never needed or wanted, but now seemingly will be required to use.
I can't believe these comments - passkeys are pretty easy to understand and most platforms allow you to add multiple. Not enough for truly one-passkey-per-device, but if you use a password manager that syncs passkeys, or hardware passkeys it's fine - it's easy, quick, and more secure than any password can ever be (mitm resistant).

I think the confusion with passkeys comes from that fact that everyone wants to own you so you have to be mindful if this passkey is being stored on the OS, the browser, sync'd between devices through google or apple, etc.

personally it works well for me as a way to login.

however, lately the anti-bot/spam shenanigans from big tech has ruined any ux work they have spent trillions on.

<rant>

one fine day, i was trying to log into my google account at google's office. for some reason their internal wifi was serving the internet through a corporate vpn, which was based out of the US. this tripped their security system, which then made me jump 3-4 hoops to log in back to my account. i recall sms verification (where you send them a code), some part where i had to scan a qr code and open on my phone (not logged into google btw), and the usual 2fa, among others.

likewise ticketmaster asking for verification for a decently used account over the years out of the blue. this is when booking a new ticket from a residential internet without any shady business. was made to reset my password three times in a row, and still got blocked!!!

</rant>

the false positive rate of these systems have reached a boiling point at some instances. yet they don't seem to stop the spammers and scalpers, but cause great pain to regular folks who don't pass the sieve. passkey-based verification is just a symptom of the larger problem.

PS: don't even bother using a non-normie browser, as it is a sure-shot way to get restricted, even on this website. it is as if we are all using tor browser if it is not the latest chrome.

Stop thinking of them as alternatives to passwords. That is something they do, incidentally. Really, they are an alternative to normal TOTP 2FA (and shudders SMS 2FA). Those were already dependent on an app on a single device, or a password manager. And now, you can have the security of that, automatically used with biometrics. It is only because they are so secure, due to being a cryptographic key, that they can replace passwords.

They really should come up with a way to transfer them across devices/password managers though.

One of the worst technologies I've had the misfortune of being forced to use honestly. It's always confusing and always breaking or not working as I expect across my devices?
