hachyderm.ioIf you actually read the “Passkeys are a trap. Do not use them.” post going around, you’ll find a transparent attempt to clumsily string together a conspiracy.
The post is predicated on the idea that a feature of WebAuthn called “attestation”, which is only used in high-assurance and usually corporate scenarios, and usually with physical hardware security keys, will be leveraged to hurt people, somehow.
The post posits that a website like X will bait and switch users: first, you get a passkey. Then, later, scary “attested” passkeys! This simply isn’t possible to do because attestation isn’t supported on the web for mass market, consumer authentication.
Attestation for passkeys (software-based, syncable credentials) is antithetical to their mass market goals, and would freeze out independent, non-corporate-backed credential managers. It’s an explicit non-goal of the designers of passkeys, who work together in a forum anyone can join.
And trust me, websites and apps like banks repeatedly asked for attestation at the beginning of the industry’s passkey journey. The platforms, browsers, and credential management apps have held firm that the goal of passkeys is reducing phishing and **not** some kind of trusted computing scheme. (And I will note: over my dead body!)
Besides the theory of the case being fundamentally wrong, there are several things that make the post disqualifying in terms of arguing something useful or important in the realm of security, privacy, and user authentication:
1. Intentionally presenting things that are complicated as inherently suspicious. (Delivering security by design can be complicated, yes!)
2. Describing TOTP as a “great solution” for adding security to a password-based account. When the most common threat model on the web is phishing (a word the post never mentions!), TOTP hardly buys you _anything_. TOTP is phishable.
3. Seeming to be unbothered by how many logical leaps are being taken without actually understanding the topic being discussed.
There are bad things happening in tech and untrustworthy people and companies do exist, but they’re largely in the AI space, not the “let’s stop people we love from getting compromised through phishing” space.
A rebuttal to an anti-passkey, pro-TOTP post that has made the rounds on Lemmy as well.


I’m using GNU pass, it doesn’t support passkeys. I’m using Arch with Firefox. When a site requesting a passkey, Firefox says touch the key. I don’t know what to do so I cancel the process and search for a workaround.
For example npmjs.org, they require passkey for publishing packages, so I rather have to create an API token which supposed to be for CICDs and publish the package with that instead.
It’s f*cking awkward. I have a secure password manager, offline, nowhere shared, even the passwords are encrypted. Don’t force passkeys on me for no reason, I was secure before as well. And even if you do, at least it should work. As always Linux users left behind.
“Even the passwords are encrypted” I would certainly hope so! Seems like the bare minimum for a password manager 😄
Yeah but most of them are just opened up and stays like that, e.g. I open an app and it can read my gnome keyring passwords
Without browser extensions, Firefox only supports hardware passkeys, so it’s waiting for you to plug one in and touch the “attentive” button.
I’m another gnu pass user, made a similar complaint in one of the other threads. I see dessalines claiming here that they use passkeys just fine with a 'FOSS" password manager. I guess that means it’s up to us to contribute an implementation of some kind.
There’s a discussion/issue on the codeberg hosting of the passff extension that seems to lay out what is needed: https://codeberg.org/PassFF/passff/issues/581
Thanks 🙏
How can the service provider tell, though?
The point of passkeys is to create an authentication flow that is easier for users to keep secure. The question, then, becomes whether a service provider should make user authentication decisions based on the worst case scenario, best case scenario, or average case scenario. Passkeys are a reasonable way to make sure almost all of your users have secure login credentials, even if the best of the best users would have just as secure login credentials with traditional passphrases.
