Now you can unlock your iPhone with your Apple Watch with the Public Beta versions of iOS 14.5, iPadOS 14.5 and watchOS 7.4.
With iOS 14.5 public beta and watchOS 7.4 public beta, you’ll be able to test the new iPhone unlocking feature with Apple Watch. This feature aims to make unlocking an iPhone much easier when you are wearing a face mask, as your Apple Watch will authenticate for you.
On the Watch app on your iPhone, select Passcode settings and enable ‘Unlock with iPhone’.
On your iPhone, select Face ID & Passcode within Settings, then enable the Unlock with Apple Watch feature.
