Introducing Knock 2.0
Knock and Apple Watch are a match made in heaven. Knock 2.0 takes full advantage of Apple Watch, making unlocking your Mac faster and more secure than ever before. When you put on your Apple Watch, Touch ID will ask for your fingerprint. After that, you can unlock your Mac from your wrist with just one tap – no Touch ID required! It’s all the security of two-factor authentication, but all the convenience of Knock.
