Passkeys are built on the FIDO2 standard (CTAP2 + WebAuthn standards). They remove the shared secret, stop phishing at the source, and make credential-stuffing useless.
But adoption is still low, and interoperability between Apple, Google, and Microsoft isn’t seamless.
I broke down how passkeys work, their strengths, and what’s still missing



You can store Passkeys in open source password managers.
I don’t know most of my passwords, so the step to passkeys doesn’t feel like a big one. I also really like the flow of pressing Login; Bitwarden pops up a prompt without me initiating it; I press confirm. Done, logged in, and arguably more secure due to the surrounding phishing and shared secrets benefits.
Sure, they probably work great when you have your *passkey manager on the device, but that’s not when I need to have backup routes into my accounts. When using a new device, or someone else’s, having even a complicated password that can be typed or copied-pasted has way more functionality.
As far a I can tell, using passkeys would only risk locking me out of my accounts. Everyone else is already effectively locked out.
I can access my password manager via the browser from any device.
Can’t you access your password manager from a web browser? Or your phone?
Oops, meant passkey manager, fixed it.
Isn’t that the same thing? All my credentials & passkeys are in the cross-platform password manager available from all my devices & any web browser. Passkeys even have a cross-device flow, so we can just scan a QR code & use a phone to sign into anything.
Manually keying in a password just feels so boomer.
Yeah the moods in this thread, like
“[I don’t understand this]!”
“[I don’t trust this]!”
“[It doesn’t fix everything]!”
“[This doesn’t benefit me]!”
“[What’s wrong with old way]!?”
And like, all valid feelings… just the reactions are a bit… intense? Especially considering it’s a beta stage auth option that amounts to a fancy version of the old sec key industry standard, not the mark of the beast.
Because we all know it will eventually go from a “neat” to mandatory with vendor lock-in for no other reason than “fuck you”.
We’ve all seen it a few hundred times now with X, and Y.
I get a few daily pop-ups for “Want to use a pass key”. One from my bank. No I don’t want to link my fingerprint to my bank account especially in a way that will lock me out when I replace my phone.
Remember folks: Biometrics (What you are) is not constitutionally protected but what you know is (for now at least).
You do not need your fingerprint or any other biometric to use a passkey.
You do not lose access to passkeys when you lose your device.
I was never prompted to do such a thing. It always just told me to plug in my phone (and even that didn’t work).
