Unlock your iPhone Whenever you remove your Apple watch, you’ll be prompted to enter a passcode that allows you to gain access to your watch. It doesn’t take very long to enter the passcode, but sometimes you don’t want to mess with the whole process, and you’d rather just avoid pressing the tiny little buttons. When setting up your Apple Watch, it will ask you if you’d rather unlock your it using your iPhone. We recommend you select ‘yes’. Now you can unlock your iPhone and your Watch at the same time. If you set up your Apple Watch without reading these tips first, there’s still a way to select this feature. With your Apple Watch connected, open the Apple Watch companion application on your iPhone and go to the Passcode menu. Here you can enable the “unlocking with your iPhone option” without having to reset your watch.
