A fingerprint scan is the best example of the 'Something you are' factor because it utilizes a unique physical characteristic of the user, which is considered a biometric method. These types of methods are based on the individual's unique biological traits and are therefore difficult to replicate or share, enhancing security. A hardware token and an access badge are examples of 'Something you have,' while a PIN and a password are examples of 'Something you know.' Voice recognition could be considered a 'Something you are' factor, but biometric methods like fingerprint scans have wider acceptance and typically provide stronger security due to decreased error rates and lower chances of mimicry.
