    What are passkeys?

    ~15s
    Passkeys replace passwords with biometric authentication (fingerprint or face scan). Instead of typing a password, you verify with your face or fingerprint. No password to remember, steal, or phish.

    How they work

    ~15s
    When you create a passkey, your device generates a unique cryptographic key pair. The private key stays on your device (never shared). Logging in uses your biometrics to unlock this key. No password ever crosses the internet.

    Why they're more secure

    ~15s
    Can't be phished — there's no password to type on a fake website. Can't be stolen in data breaches — the key only exists on your device. Can't be guessed — there's no password to brute-force.

    Who supports passkeys?

    ~15s
    Google, Apple, Microsoft, Amazon, PayPal, eBay, Best Buy, Kayak, and hundreds more. The list grows weekly. Check passkeys.directory for a complete list of supporting sites.

    How to set up a passkey

    ~15s
    When a website offers passkeys: go to account settings > security > create passkey. Your device prompts for Face ID, Touch ID, or fingerprint. Done. Next login, just verify your identity biometrically.

    What about my existing passwords?

    ~15s
    Passkeys supplement passwords — you can use both. Start creating passkeys for important accounts (email, banking) while keeping passwords as backup. Your password manager syncs passkeys across devices.
