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



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.
If we cut and run every time a big corporation “embraces” a new standard, just to lessen the pain of the day it’s inevitably “extinguished,“ we’d miss out on quite a lot.
This standard was open from the start. It was ours. Big corps sprinted ahead with commercial development, as they do, but just because they’re first to implement doesn’t mean we throw in the towel.
