Passkeys use something called public key cryptography. They have your public key. And because it’s public, it doesn’t matter if anyone gets it. That public key and your private key combine to validate who you are.
But how does that work? Wouldn’t they have to know something besides the public key that’s unique to you? No. That’s the brilliance of it.

Episode transcript:
Internet security. It’s bad. Data breaches are constant, and peoples passwords are sold on the internet like cherries from a roadside cart.
Some of that is because of passwords. We rely on humans to pick passwords and they aren’t so good at it.
We need to get past passwords. Passkeys are one of the most promising ways to do this. We have a whole episode about how they work, but in short, you keep the key on your device and only use it when you need to log in. That way you don’t have to remember a password, meaning you won’t pick an easy one to guess, and more importantly the company you’re logging into doesn’t have your password, or anyone’s, so it’s not a big juicy target for attackers.
But wait, you may say? How does that work? Passkeys use something called public key cryptography. They have your public key. And because it’s public, it doesn’t matter if anyone gets it. That public key and your private key combine to validate who you are.
But how does that work? Wouldn’t they have to know something besides the public key that’s unique to you? No. That’s the brilliance of it.
