But the latest update, which is part of a developer beta test, is likely to be rolled out widely soon, an iPhone will be able to communicate with a synced Apple Watch when the phone is increased to use Face ID.
When authentication is complete – the devices must be close to each other – the iPhone will automatically unlock and the Apple Watch will vibrate.
Apple said users must sign up for this feature.
For security reasons, the update only works to unlock the phone; users still need to enter a passcode to make transactions via Apple Pay, the App Store or iTunes if wearing a mask.
The latest update is both another step forward in supporting the wearing of masks during the pandemic and a potential incentive for Apple customers to buy a smartwatch, or at least use the one they have more often.
