Authentication Methods

Abstract

Every day, people encounter some sort of authentication, whether it be logging into a computer using their username and password, unlocking their phone, entering their PIN to access a bank account, swiping a card for access to a building, and more. We are investigating the most reliable and secure methods of authentication by analyzing studies on the subjects. We present traditional methods such as passwords and PINs, as well as more recent technology, such as facial recognition, fingerprints, and more. We compare the different methods in multiple situations.
