FBI agents recently forced a man to unlock his iPhone using the device's built-in facial biometric unlocking system—Face ID—according to Forbes.
Federal agents obtained a warrant to search 28-year-old Grant Michalski's house as part of an ongoing child-abuse investigation, Forbes reported.
The FBI forced Michalski's face in front of his iPhone X in order to use his facial biometrics to unlock the device. Investigators then discovered evidence in his chat history—and photos in his possession—of child pornography.
