    Passkeys Explained

    The end of passwords (mostly).

    What a passkey is

    A passkey replaces a password with your face, fingerprint, or phone PIN. The "key" is stored on your device. Sites verify it without you ever typing a password. Cannot be phished. Cannot be guessed. Cannot be reused on another site.

    Why they're safer

    • No password to type — no keylogger or phisher to steal.
    • Each site gets a unique key. One breach can't affect others.
    • Bound to YOUR device. Hacker on the other side of the world can't use it.
    • Backed by Apple, Google, Microsoft, Amazon, PayPal — they're the future.

    How sign-in feels

    1. Visit website. Type your username (or it's remembered).
    2. Phone or computer asks "Use Face ID to sign in?"
    3. Look at phone or touch fingerprint. Done.
    4. No password. No 2FA code. No typing.

    Sites supporting passkeys (2025)

    • Google, Apple, Microsoft.
    • Amazon, eBay, PayPal, Best Buy, Target.
    • Facebook, Instagram, X (Twitter).
    • GitHub, Adobe, TikTok.
    • Banks slowly rolling out — Chase has it, others coming.
    • Total: 1 billion+ passkeys created.

    Set up your first passkey

    1. Log into Google or Apple or Microsoft account on a phone.
    2. Account → Security → Passkeys.
    3. Tap "Create a Passkey".
    4. Confirm with Face ID, fingerprint, or PIN.
    5. Done. Next sign-in won't need a password.

    Where passkeys are stored

    • iPhone — iCloud Keychain. Syncs to iPad and Mac.
    • Android — Google Password Manager. Syncs to all your Google devices.
    • 1Password / Bitwarden — store passkeys. Syncs across devices regardless of platform.
    • Hardware key (YubiKey) — most secure. Plug into USB.

    Don't panic

    Passwords aren't going away tomorrow. Passkeys add an option — they don't force change. Try them on Google or Amazon first. If you like it, expand. Most sites still have password as a backup option.
