Your Apple Watch can unlock your iPhone. It needs a passcode, and it has to be unlocked, on your wrist, and close to your iPhone. To allow Apple Watch to unlock your iPhone for Siri requests or when an obstruction prevents Face ID from recognizing your face, do the following:
- On iPhone, open Settings and tap Face ID & Passcode. Then enter your passcode.
- Scroll down to Unlock With Apple Watch and turn on the setting for your watch.
If you have more than one watch, turn on the setting for each one.
- To unlock your iPhone, make sure you’re wearing Apple Watch and wake your iPhone. Glance at its screen.
Apple Watch taps your wrist to let you know that your iPhone has been unlocked.
Note: To unlock your iPhone, Apple Watch must have a passcode, be unlocked and on your wrist, and be close to your iPhone.
