What does Face ID enable users to do on compatible devices?

Face ID is a facial recognition technology designed by Apple that allows users to unlock their compatible devices securely and conveniently. By using advanced sensors and photography to map the user’s face in three dimensions, Face ID not only streamlines the unlocking process but also enhances security, ensuring that only the authorized user can access their device. This biometric identification method has replaced Touch ID on newer iPhone models and is used for various secure functions, including making payments and logging into apps.

The other options relate to functions that either do not utilize Face ID or are unrelated to its capabilities. Authorizing app downloads and making photocopies can involve other methods of identification or processes that do not include facial recognition. Similarly, transferring files usually relies on other technologies such as AirDrop or cloud services, not on Face ID. Therefore, the ability to unlock devices using facial recognition is the key feature of Face ID that distinguishes it from other functions.
