What are the two fast and secure methods for accessing your mobile device?

An increasing number of smartphones and mobile devices have facial recognition and fingerprint readers that can identify you more quickly than you can type numbers on a screen. The camera, sensors, and dot projector on your smartphone are used in facial recognition to create a 3D map of your face. The 3D map is then used by the phone to identify you during subsequent transactions. Regardless of the technology used (capacitive, optical, or ultrasonic sensors), fingerprint readers create a map of your fingerprint and, like facial recognition, compare it to your body. In just one second, you can authorize a transaction or obtain access to a device using either one. PIN codes are a number that you enter to gain access. They can be entered quickly, but they are less secure than biometrics (fingerprint scanning and facial recognition) because they can be guessed. Although being fast, using a swipe to unlock a mobile device is not secure.
