A beginner-friendly explainer on how passkeys work using public/private key cryptography, where a private key stays on your device and a public key is shared with the website. Covers the core handshake mechanism, compares passkeys to passwords and password managers, and offers a measured take on their real-world trade-offs — including device dependency and phishing resistance — without overselling them as a universal solution.
