How Passkeys Work - Computerphile?

Passkeys are like super-cool keys that help you open your digital doors without needing passwords.

Imagine you have a special key that only you have. When you want to log into something, like your favorite game or app, it asks for this special key. But instead of typing in a password, you just show the key, maybe by tapping your phone or waving it near a computer.

Think of passkeys as secret handshakes between your device and the thing you're trying to log into. When you set up a passkey, your device creates a unique pair of keys: one stays with the app or website (like a digital lock), and the other lives on your phone or computer, like a magic key that fits only that lock.

Next time you want to log in, your device uses the secret handshake to prove it’s you, no need for passwords! It’s like when you use a fingerprint scanner, it knows it's you without asking for a password. Easy peasy!

So passkeys are just fancy keys that help you open digital doors faster and more securely. No more remembering complicated passwords, just tap or wave your device, and you're in!
