Security: Passwords & Passkeys

Question 1

Why are passkeys more secure than passwords?

A. They use XProtect to create signed certificates in iCloud Keychain.
B. They are less vulnerable to phishing.
C. They work on Apple devices only.
D. They generate a unique shared secret for every account on the device.

Answer 1

B. They are less vulnerable to phishing.

Trick answer note:

“D” seems correct, but it’s not. While passkeys do involve cryptographic key pairs, the phrasing here is misleading. The unique key pair is for each account and website, not just the device.
