  Answers Explanation & Hints: A smartphone should use the screen lock feature to protect sensitive information. To unlock the device, a password or passcode is required. Smartphones also support pattern locks, or swipe locks. Pattern locks eliminate the time it takes to type passwords or pin numbers. You just need to join the dots (numbers) on the keypad in a specific pattern and the phone is unlocked. Many modern mobile devices come with biometric authentication capability such as fingerprint sensors and face recognition for unlocking the device.
