A passkey is a cryptographic credential stored on your device. Instead of a password, you authenticate with Face ID, a fingerprint, or your PIN. Faster and more secure.
Setting up a passkey:
Go to Settings
Under Passkeys, click Add passkey
Give it a name (for example, "Work MacBook")
Follow the prompt to register on your device
Add multiple passkeys (one per device) and remove them individually.
Logging in: On the login screen, click Sign in with passkey. No password needed.
Security: Login attempts are rate-limited to 5 per minute. Accounts are temporarily locked after repeated failed attempts.
