How to Unlock iPhone and Mac with Apple Watch

Your Apple Watch can do more than mirror your phone’s notifications or track your activities. It can also be the key to unlocking both your iPhone and your Mac.

The feature is especially handy when you’re wearing sunglasses or have part of your face covered, so using Face ID will be tricky. Also, in the case of your Mac, you will no longer have to enter your password after each alarm clock. Let us show you how to unlock your iPhone and Mac with an Apple Watch.
