Passkeys are special digital keys stored on a device that make use of biometric authentication for a secure sign-in experience. To explain in simple terms, Passkeys will let you to sign in on a website without typing in your password. Instead, you’ll be able to log in just using Face ID or Touch ID, making the process far more simpler and faster.
Passkeys depend on a long-standing security practice that make use of a pair of encryption keys. In this case, all Passkey you create has both a public key and a private key, which are paired with each other. When you set up a Passkey, the public and private keys are created. Your device sends the public key to the website you want to sign into and then uses the private key which never leaves your device, unlike a password to verify that you are really you.
Below are the benefits of using a Passkey instead of a password:
- There’s No Password to Steal: Hacking to steal your password won’t work because Passkeys work with a key pair that can only be unlocked when together and with biometrics. That’s very secure!

- Compatible with Non-Apple Devices and Security Devices: You can use PassKeys on your Apple devices or non-Apple devices through a shared QR code even though they are stored on your Apple devices. Passkeys can also support security fobs used in several corporate environments.
