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.

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).

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.

Also:

  1. Bio auth isn’t necessary. It’s just how Google/Apple do things on their phones. It’s not part of the FIDO2 standard.
  2. It works with arbitrary password managers including FLOSS and lots of hardware options.
  3. Passkeys can sync to arbitrary devices, browsers, device bound sessions, whatever.
