It surely makes your phone safe, but the question is, for how long

The fingerprint scanner on smartphones have changed the way we use our phones. A new study has even shown that the convenience of a fingerprint scanner has made more people lock their phones now than ever before. Keying in a password is cumbersome and inefficient while just rubbing your finger against a sensor is simple and works like magic. It also makes you feel that your device is now as secure as Fort Knox and you and only you can get access to it. Thus, people are adding things on their phones they would never even dream of having before.
