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

While the lock-in issue is annoying and a good reason not to adopt these, the device failure issue is a tech killer. Especially when I can use a password manager. This means I can remember two passwords (email and password manager), make them secure, and then always recover all my accounts.

Passkeys are a technology that were surpassed 10 years before their introduction and I believe the only reason they are being pushed is because security people think they are cool and tech companies would be delighted to lock you into their system.

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.

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.
