Now, there are 3 most popular yet secured ways to log in to your smartphone other than the old methods like usual passwords, swipe, pin code and pattern options.

These are the fingerprint sensor, face recognition and a dedicated iris scanner up front.

Both the face recognition and iris scanner cannot be active at the same time, so you have to choose one. This implies that the front camera sensor actively reads the object up front at the time of screen awakening so in order to clear the confusion for the sensor that what it conceives to unlock i.e. face recognition or eye pattern, the developers refrain from using both the technology at the same time.

These three technologies you can use to unlock your devices, to know more extensively about these latest technologies, check out the full article:
