Apple is developing a new security feature that would automatically lock an iPhone when it detects that the device has been taken from its user, according to code seen by 9to5Mac. The feature is designed to limit unauthorized access to sensitive data if the phone is stolen.
How the Feature Works
The system uses the iPhone's built-in sensors, including the accelerometer and gyroscope, to detect a sudden snatching motion. To improve accuracy, the feature may also check the distance from a paired Apple Watch, which can help confirm the device has moved away from its owner's wrist.
Once a potential theft is detected, the system will assess whether the iPhone is in a familiar location, such as the user's home or workplace, or connected to a known Wi-Fi network. If the device is determined to be in an unfamiliar environment, it will automatically lock the screen and restrict access to sensitive areas managed by Stolen Device Protection.
Security Measures
When triggered, the feature requires biometric authentication (Face ID or Touch ID) for access to stored passwords, credit cards, and other sensitive data. It also imposes a one-hour delay for major account changes, such as resetting an Apple Account password. This measure is intended to prevent thieves who may have observed the user's passcode before taking the device.
Development Status
The feature is currently under active development based on code references found in Apple's software. No official announcement or release date has been provided by the company.
Industry Context
A similar feature, called Theft Detection Lock, is already available on Android devices.
