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.
