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.

I can access my password manager via the browser from any device.

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.
