PSA for iOS Android users everywhere: it's fine to use biometric authentication to unlock your device. It helps you choose better passwords. So instead of turning fingerprint and face scans off completely, when you find yourself in a less secure environment, simply press the power and volume up buttons simultaneously for a few seconds. On iPhones, your phone will immediately require a password. For Android users, you'll need to click the lockdown button presented on the screen. Then, practice the move a couple times per week each week. #UsableSecurity
