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

if it undermines or circumvents my fifth amendment right not to testify against myself, then I'm not interested in ending the use of passwords.

Okay, so long as a passkey is something I can memorise. Otherwise, it's significantly worse than a regular password (assuming you use good passwords and don't reuse passwords etc).

It seems like they want to tie it to a physical computer (like the one in your pocket), which sucks big time. What happens if I don't have access to that computer at all times, or it breaks, or is lost?

I'm planning on getting rid of my smartphone for something that just does calls and texts for example, because I'm sick of how unhealthily reliant I, and everyone, have become on this thing, and I want to be more connected to the real world. What then?

My brain is the best place to store passkeys, it can't be hacked, stolen, lost, etc, unlike every other option. It's easily capable of storing lots of randomised unique passwords for each service (surely I'm not the only one that can do this?). It's the clear winner.

Hardly anyone supports it: https://www.passkeys.io/who-supports-passkeys

So to use it I will have to log in with my google/microsoft account everywhere? Thanks but no thanks.

I've used it with many sites not on that list. Including this one. It's not comprehensive.

No, you do not need Microsoft/Google account.

All I know is a few months back someone setup a passkey on a shared google account at my job and now nobody but knows what the password for our email is. I can use the passkey to sign in with my phone, but only I can do that.

My company’s online product uses passkeys (I implemented it) more as a convenience method for login. 2FA is the base standard, and authenticated users can create a passkey for each device they want to use. Subsequent logins can then use the passkey or 2FA. Rather than having to dig out my phone, open the authenticator app, and put in the digits, I can simply use the fingerprint reader and I’m right in.

That doesn't sound like a TOTP vs passkey situation though. It sounds like the program just releases the passkey when you give it the fingerprint. There wouldn't be anything stopping the program from generating a OTP and passing that along when you identify with the fingerprint.

I think a big issue is how difficult it can seem to be to get easy access to TOTP codes, like in your example digging up your phone. But that's more of a browser/operating system failure for not implementing a way to generate those codes like they can already store usernames and passwords.

seems like too much messing around to make it a widespread solution.

What am I dependent on to access by stuff if I use a passkey? A smart phone?

I like passkeys but ONLY as the second factor. Using them as the primary makes no sense in majority of cases.
