Stolen Device Protection is a security feature designed to safeguard user data if a device is lost or stolen. When enabled, it requires additional authentication - such as Face ID, Touch ID, or a strong passcode - before allowing sensitive actions like changing account passwords or accessing stored credentials. This protection becomes especially stringent when the device is detected in an unfamiliar location, adding time delays and restricting certain operations. These measures help prevent unauthorized access to personal information and critical device settings, even if someone else has physical possession of the device. Stolen Device Protection is commonly found on modern smartphones and tablets.
