How to set up a passkey

A passkey lets you sign in with your fingerprint, face, or device PIN instead of a password. It's stored on your phone or computer and can't be phished, guessed, or reused on another site.

Adding one

1. Sign in above the usual way — with your password, or by emailing yourself a sign-in link. You have to prove who you are once before you can add a passkey.
2. Once you're in, find the Add a passkey button on your profile page (or the dashboard, if you're staff).
3. Your device will ask you to confirm with a fingerprint, Face ID, Windows Hello, or your screen lock PIN. That's it.

Using it

Come back to this page and press Sign in with a passkey. You don't need to type your email — your device will offer the account it has saved and ask you to confirm. You'll be signed straight in.

Good to know

• You can add more than one — say, your phone and your laptop. Add a second before you rely on the first.
• Passkeys saved to iCloud Keychain or a Google account follow you to your other devices automatically.
• Your password and sign-in links keep working. A passkey is an extra way in, not a replacement, so losing a device never locks you out.
• A passkey created here works on scan-if-found.com only. Our sister site scan-if-found.org needs its own.
• Passkeys need a modern browser on iOS 16+, Android 9+, macOS Ventura+, or Windows 10+. Older setups can keep using a password.
