• You need to make sure your watch has Wi-Fi, Bluetooth, a passcode, and wrist detection configured.
• When you turn on Unlock with Apple Watch on iPhone, it will be unlocked automatically when you raise your wrist or tap the screen.

If you wear a face mask, the iPhone’s face ID is less effective in unlocking your cellphone automatically than it used to be. If you have an apple watch with Watchos 7.4 or newer and iPhone with iOS 14.5 or newer, you can still avoid entering a passcode: Apple Watch can automatically unlock your cellphone for you.
