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’s more convenient to be insecure than secure, users will pick insecure every time. There’s a reason there are so many bad password in the top passwords in breach dumps.
I have to tell myself every time I go through some of my login flows that inconvenience to me means more so to an attacker, but most people don’t have an adversarial mindset and just want it to work.
User inconvenience is not at all the same thing as security.
No, but the two tend to be correlated.
Example, MFA authentication is a security feature, but inconvenient as shit with low or no lifetime. Same complaints about short lived sessions on app sites. Especially when every login requires MFA…
MFA can be a variety of different things. In the case of passkeys, a prompt comes up on the screen, you click it, and that’s it. It’s both secure and convenient. That’s why it’s great.
