Note that attestation can only be required during credential registration; at login time it's not possible to retroactively require attestation if it wasn't obtained during registration. And browsers will throw up a permission prompt if a website requests attestation. Are Netflix and Twitter currently requesting attestation when people register passkeys, and rejecting the registration if the user declines the permission prompt? I very much doubt it, since Apple's passkey implementation doesn't support attestation.
Therefore, the author's scenario that sites will wait until most of their users are using attested passkeys and then "flip the switch and start rejecting non-attested passkeys" isn't very plausible.
Attestation is certainly a stain on the WebAuthn spec, and it would have been better if Chrome and Firefox didn't support attestation (unless perhaps the browser is enrolled in enterprise management), but this blog post is presenting a hypothetical and unlikely scenario. That's not a good enough reason to recommend TOTP instead, given that TOTP is vulnerable to phishing and passkeys aren't.
If consumer-facing sites start requesting attestation when registering passkeys, they deserve to be vigorously called out, and maybe then the recommendation to use passkeys should be revisited. But until that happens, don't tell people not to use passkeys.

Sorry, bit this is just the standard "boil the frog" playbook that tech companies always use for user-hostile features. It's usually:
1) There is this new entirely optional feature, but it's not relevant to you, so feel free to ignore it.
2) The feature is now active by default, but no worries, there is a simple button for you to opt-out.
3) The feature is active by default, but because we value our users, there is an option in the advanced settings to deactivate it.
4) Our data shows that 99.9% of users activated the feature, but if you belong to the handful of diehards who still refuse to use it (rolls eyes), you can use this obscure command line flag or about:config entry to turn it off
5) Managing opt-out infrastructure for the feature has significant maintenance and security cost that we feel, we can no longer justify. Therefore, effective in three months, the opt-out flags will stop working and the feature will become mandatory. According to our metrics, this will affect 0.0001% of our users, so no disruption is expected.

There's also another scenario - annoy most users into using passkeys, then say "well everyone is using passkeys already, we don't need passwords anymore", and _then_ slowly start requiring attestation. Really I'm not one to look for conspiracy theories, but with the recent pushes around e.g. chat control, it's not that far fetched to assume someone pushes for more control over users' accounts

I sort of started skimming when the article was saying industry solved the problem with text messages and TOTP. I think there are several arguable problems with Passkeys as implemented, but to argue TOTP is equivalent is going to leave lots of people vulnerable.
The protections against MITM you mentioned is probably the biggest one, but the other one in the back of my mind is TOTP is a shared secret. So a compromise of the server side allows impersonation of users undetected, which can be a big problem. Maybe I'm over reacting because no company has ever lost a copy of it's database and they're all super secure. But, imagine trying to argue as a user I didn't do a thing when there is an audit log saying we challenged the user for TOTP and it was provided, was definitely the users fault.

Because it prevents an attacker from stealing the password. It's both extremely hard to "steal" a passkey, and to phish a login from one. Neither of those are true for passwords, and TOTP only partially solves the stealing part.
Passkeys aren't solving for security nerds who like portability and have 30 character long passwords, they're solving for grandpa who will happily read their bank's 2FA SMS to the "bank" over the phone. The FIDO alliance has literally billions more of these users than they do users who know what hardware attestation is and how it impacts their auth workflows.

I've yet to voluntarily enable passkeys, for the main reason that I want portability, and not to be tied to any single device that can be lost. I want to be able to backup and lock my credentials in a safe. I also want to control the strength of my credentials for different services, and I don't consider my thumbprint used to unlock my phone to be as strong as a long password in a password manager.
The first time I was forced to use a passkey implemented within the vendor's app (3rd party password managers were not an option). I quickly closed that account.
The second time was an app that popped up a passkey opt-in in the middle of a bunch of transaction screens. I quickly realized the error, but there was no easy undo. The opt in was one green button in the middle of the screen. Turning it back off required digging through settings to find the security option to disable, and then confirm my choice multiple times. That process also signed out all my other devices.
The fact that companies are resorting to dark patterns and forced requirements, where my money is held hostage, should be pretty good evidence of how poorly the passkey rollout is going.

This is a (very long and) well-written treatise against passkeys in their common and disparate forms. It's worth reading, and brings up several interesting and often concerning points.
I don't agree with the conclusion, though.
TOTP is great, flexible, and keeps the user in control; however, using a passkey in a flexible password manager (Bitwarden, keepass, 1Password, etc) really does continue to give the user control. And the user experience is dramatically easier than filling in TOTP codes.
To advocate for TOTP over passkeys, we're already relying on an application to generate those numbers (authenticator apps, password managers, etc). I see no reason to not simply continue using those pieces of software to manage passkeys, too.

Sure, but if you read the article you would know that deal can (and will undoubtedly) be altered. The passkey issuer can demand that the passkey be hardware-backed, and I've already run into passkeys that cannot be stored in bitwarden out in the wild (i.e. they REQUIRE that I use a TPM-backed store in my computer). Eventually it will be a particular TPM-backed store running on an attested platform. Now that's not generally the case today, but make no mistake, that IS the ultimate goal... You will only access valuable services from devices that you fundamentally have no control over (e.g. locked down OS's with attestation before you can access X,Y,Z), so that you can't steal from netflix, skip the sponsor segments on youtube, block ads in your web browser, etc. etc. etc. If you want a preview of how this might all work from the technical side, just look into how TEE works for large-scale GPU deployments right now.

That's simply not true. I'm able to log onto GitHub on my corporate device using a passkey that's kept in 1Password on my iPhone.
But you can be locked out if the provider decides you need to change your password after a breach, or you forget the password, or you enter the wrong password in too many times.
They’re both equally disposable. You can reset a password just like you can reset a passkey.

I completely agree that KeePassXC and other password managers give you total user control, and they do support "passkeys" -- but crucially, not all kinds of passkeys. KeePassXC has no remote attestation support, nor hardware-backing support, and nor do I think it should.
My claim is not that passkeys couldn't give you control in principle. It's that the standard readily allows for websites to prevent you from being allowed to exercise that control, and the unclear messaging and UX around passkeys means most users will not even notice should this happen.

I don’t know if it’s productive for me to talk about how a headline is off-putting, but I’m going to mention it because, well, it’s a headline, and a headline is a strong first impression.
Is the audience of this article the kind of people who are already using passkeys and like them? Because, if so, we’re starting at a deficit here. The author is out to get my beloved passkeys that have saved me so much time and pain.
Are passkeys perfect? No. Are they even very good for no-technical users? Absolutely not…they’re incredibly confusing for that kind of person if you ask me.
However, for my workflow, I’ll take them over a password+2FA type of situation where logging in is such an annoyance. The security part of the discussion is very interesting and a lot of the things in this article are stuff that I didn’t know before reading it.
The issue is that, putting on my user hat, I just don’t care. As long as my accounts are reasonably secure I’m much more concerned about ease of use and workflow.

The intended audience is people who are not yet using passkeys, or have just started (due to all the websites demanding them now) but don't really know what they are.
I apologize that the headline is provocative. I thought for a long time about how to appeal to both people who are barely aware of what passkeys are but also not put off people who like them. I considered calling them a "Trojan Horse" in the headline as I do in the body (i.e. legitimately lovely, but with a terrible and unobvious problem) but "trojan" has another connotation in computer security.
Nonetheless, I said what I meant. Convenience is how they get you. This convenience didn't have to come with a trap, but thanks to the way it was designed, it does.

Hard disagree. Phishing is a major problem. Passwords+OTP are phishable[1]--passkeys are not (the signature is bound to the domain and cannot be forwarded). That alone makes passkeys worthwhile for the vast vast majority of consumers. This is not a theoretical threat model. You simply cannot realistically expect even a savvy consumer to be able to save themselves from phishing all the time. One mistake and they are fucked.
If you write a long article about the merit of passkeys and there is no occurrence of the string "phish" in your article, I am afraid I cannot take your rant seriously.
Again, this stuff is not merely theoretical. YubiKeys have been a thing at Google and other major tech companies for almost two decades now and the effects are well-studied.

Passkeys make it feel like the site is trying to get more info about me; it seems harder to maintain multiple accounts with passkeys. They feel worse for anonymity than a password where you know exactly what you're pasting into the site.

My understanding is that TOTP and physical security keys both share very little information about you. Perhaps passkeys, being part of a standard that the FIDO Alliance keeps updating, may some day be expected to reveal considerably more information.

I've been complaining about passkeys for a long time and it was driving me crazy that it seemed to be the one thing that Big Tech, tech-savvy people, and normies were all on the same page about. The recent PR push a few months back was overwhelming.
Passkeys in theory are great, but the capabilities of the spec are worrying. Defaults can and do change, and when they do, so follows 99% of the population, and then you find yourself either getting blocked out of services because your hardware/software doesn't comply, or you give in.
But on the other end, it might not matter anyways. Apple, Google, Cloudflare, are already pushing similar garbage and now you increasingly have to scan a QR code that verifies your mobile hardware to use a desktop.

If you also support TOTP and physical security keys as an alternative to passkeys, that should be enough to provide a stable long-term alternative for users of FOSS devices. And of course, RP-side you can choose to never require the remote attestation flag to be set.
Convenience is precisely the thing that big tech established tech platforms want to reward their users with to keep them around. The undeniable convenience of passkeys didn't have to come with a standard that is threatening against unattestable devices like my Linux phone. But it does, and that means passkeys are a way that the industry can discourage people away from using non-Google/Apple/Microsoft-approved devices.

Because you or someone needs to publish "<digital_signature>" in a way that cannot be forged, stolen, MiTM'd, or otherwise compromised. Basically the key generating that signature just becomes another password, far more difficult to use in practice, and sharing all the same disadvantages.
So no one implements it for site-local login. Even the biggest sites like Amazon, for example, still use old-school passwords+2FA.
The way secure auth works for small sites is that a third party[1] authenticates you, who the website trusts more than mere users. And that's where all the complexity comes up. You need something secure stored on your known-secure device, a password alone won't do.
[1] In practice Google or Meta. Occasionally Apple or Microsoft. Everyone else is noise.
drhagen 20 minutes ago [-]
> far more difficult to use in practice
I guess I am envisioning the user agent doing all of this. You go to a site and create click account, your browser shows a pop-up: "<website> is asking you create an EasyAuth account. Would you like to create an account on this site?" If you click yes, then the user agent does this in the background:
website: Sure you can have an account. Use this token <token> once and this ID <user_id> forever.
me: Ok, here's your token <token> for ID <user_id> and my public key is <public_key>. Signed, <digital_signature> to prove it works on my end.
Maybe generating a unique public key for each website is not substantially better than generating a password, but at least a signature cannot get stolen on the server side or in transit. You wouldn't have to change your public key if their database got slurped.
Passwords also aren't standardized, so they are pain to generate (special characters required or disallowed?). They don't reliably autofill into a website. You still have to go through a manual flow to login; user-agent doesn't just keep you logged in. I guess I would be fine if the user-agent knew how to authenticate me to every website.
Maybe this is what the passkey system was before it got designed-by-committee'd into oblivion. I am just always amazed by how complex authentication is when the user-agent should be able to handle this rather painlessly.

I agree: from an usability perspective, passkeys are awful and TOTP are excellent.
But the problem is: most of the time, the people that choose what security system you should use are the system administrators, not the end users. And they like passkeys because they are the easier for them to implement.
They require no server to send confirmation codes and no need to trust in unknown applications and their ambiguous key formats.

If you keep reading the article, you’ll see that the claim is current (unattested) passkeys are a stepping stone to “attested passkeys”.

This has always been my suspicion and I do think it’s worth worrying about.

They’re both equally disposable. You can reset a password just like you can reset a passkey.
Yeah and neither will anyone else!
My claim is not that passkeys couldn't give you control in principle. It's that the standard readily allows for websites to prevent you from being allowed to exercise that control, and the unclear messaging and UX around passkeys means most users will not even notice should this happen.
Is the audience of this article the kind of people who are already using passkeys and like them? Because, if so, we’re starting at a deficit here. The author is out to get my beloved passkeys that have saved me so much time and pain.
Are passkeys perfect? No. Are they even very good for no-technical users? Absolutely not…they’re incredibly confusing for that kind of person if you ask me.
However, for my workflow, I’ll take them over a password+2FA type of situation where logging in is such an annoyance. The security part of the discussion is very interesting and a lot of the things in this article are stuff that I didn’t know before reading it.
The issue is that, putting on my user hat, I just don’t care. As long as my accounts are reasonably secure I’m much more concerned about ease of use and workflow.
I apologize that the headline is provocative. I thought for a long time about how to appeal to both people who are barely aware of what passkeys are but also not put off people who like them. I considered calling them a "Trojan Horse" in the headline as I do in the body (i.e. legitimately lovely, but with a terrible and unobvious problem) but "trojan" has another connotation in computer security.
Nonetheless, I said what I meant. Convenience is how they get you. This convenience didn't have to come with a trap, but thanks to the way it was designed, it does.
The title put me off completely.
I’m tired of people shitting on everything. Especially without offering any advice on how to improve things. It’s exhausting to read. And apparently it’s not even the point of the article. So why is it the title?
Very very strange choice.
It wasn't a pointless rant, you're seemingly primed for something that didn't happen here.
It's a good argument that passkeys are a trap while TOTPs offer the security you need but avoid the absolute control passkeys may hand over, so stick with those.
Regarding how I feel about passkeys after reading your article, logically I am reading what you wrote and conceptually understand the trap, it’s just hard to wrap my head around what kind of situation would cause this trap to “catch” me so to speak.
I.e., the upside is real and immediate, the downside is theoretical and tied to future uncertainty.
But as for how it could "catch" you: if you use FOSS devices that are unattestable (as is the case for the LineageOS phone and Linux laptop I exclusively use), you may one day find you can't use many websites.
I'm sorry, what? Who has more than one password manager (other than a personal/work split)? That's absurd and not something anyone I've heard of would put up with
If you write a long article about the merit of passkeys and there is no occurrence of the string "phish" in your article, I am afraid I cannot take your rant seriously.
Again, this stuff is not merely theoretical. YubiKeys have been a thing at Google and other major tech companies for almost two decades now and the effects are well-studied.
[1]: I have found for some weird reason, this is often overlooked and misunderstood in the industry. People even know about SIM swaps and stuff like that, but don't realize OTP is not phishing-proof.
Although this isn't true because actually with a password you have to choose how to generate it and everyone chooses different ways.
Passkeys in theory are great, but the capabilities of the spec are worrying. Defaults can and do change, and when they do, so follows 99% of the population, and then you find yourself either getting blocked out of services because your hardware/software doesn't comply, or you give in.
But on the other end, it might not matter anyways. Apple, Google, Cloudflare, are already pushing similar garbage and now you increasingly have to scan a QR code that verifies your mobile hardware to use a desktop.
Passkeys offer the same and more security but are less of a pain for the user.
Convenience is precisely the thing that big tech established tech platforms want to reward their users with to keep them around. The undeniable convenience of passkeys didn't have to come with a standard that is threatening against unattestable devices like my Linux phone. But it does, and that means passkeys are a way that the industry can discourage people away from using non-Google/Apple/Microsoft-approved devices.
me: Can you show me my stuff?
website: HTTP 401, who are you? I understand EasyAuth 1.0, if that is good for you.
me: Sure, here's my EasyAuth 1.0: Hi <website>, I'm <user_id>. The time is <timestamp>. Signed, <digital_signature>.
So no one implements it for site-local login. Even the biggest sites like Amazon, for example, still use old-school passwords+2FA.
The way secure auth works for small sites is that a third party[1] authenticates you, who the website trusts more than mere users. And that's where all the complexity comes up. You need something secure stored on your known-secure device, a password alone won't do.
[1] In practice Google or Meta. Occasionally Apple or Microsoft. Everyone else is noise.
I guess I am envisioning the user agent doing all of this. You go to a site and create click account, your browser shows a pop-up: "<website> is asking you create an EasyAuth account. Would you like to create an account on this site?" If you click yes, then the user agent does this in the background:
website: Sure you can have an account. Use this token <token> once and this ID <user_id> forever.
me: Ok, here's your token <token> for ID <user_id> and my public key is <public_key>. Signed, <digital_signature> to prove it works on my end.
Maybe generating a unique public key for each website is not substantially better than generating a password, but at least a signature cannot get stolen on the server side or in transit. You wouldn't have to change your public key if their database got slurped.
Passwords also aren't standardized, so they are pain to generate (special characters required or disallowed?). They don't reliably autofill into a website. You still have to go through a manual flow to login; user-agent doesn't just keep you logged in. I guess I would be fine if the user-agent knew how to authenticate me to every website.
Maybe this is what the passkey system was before it got designed-by-committee'd into oblivion. I am just always amazed by how complex authentication is when the user-agent should be able to handle this rather painlessly.
But the problem is: most of the time, the people that choose what security system you should use are the system administrators, not the end users. And they like passkeys because they are the easier for them to implement.
They require no server to send confirmation codes and no need to trust in unknown applications and their ambiguous key formats.
Use proper password managers, like keepassxc. Then you have control. But problem is that not all sites support that. If you can't use the above - then yes, passkeys are bad, especially if they become mandatory.
