Passkeys Explained: The End of Passwords (sentientrant.com)

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

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.

You could also use dedicated hardware to store your keys. Any FIDO USB key will do. I have a Yubikey that cost me less than 30 bucks.

It's really handy, because I frequently use someone else's device for work. All I have to do is plug it in, press the button on the key and enter the master password for the passkey storage. It's like having a password manager on a USB stick.

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?

[–] Brokkr@lemmy.world 3 points 2 days ago (1 children)

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.

Not at all the same. I can type or dictate my passwords on any device with a keyboard. I am not reliant on an individual device continuing to work. In fact I could get all new devices tomorrow, with no access to any previous device, and log into all my accounts within minutes.

Passkeys do not allow, and specifically prevent, that.

Exactly the same with a password manager which stores passkeys. Are you reading before responding?
