Windows Hello Face is a biometric authentication feature in Windows that uses facial recognition to sign users into their device and supported apps/services. It relies on a camera system (typically an infrared [IR] or depth camera, not a standard RGB webcam) plus device drivers and system components to capture, process, and match facial data locally.

The data is processed within an isolated container protected by your processor and TPM 2.0 chip, meaning malicious apps cannot extract your facial map. Hardware Requirements for the Driver
