This section explores biometrics, where unique physical and behavioral traits authenticate identity, and the traditional role of passwords in digital safety. We'll compare their security aspects and discuss the pros and cons to understand their impact on digital security.

Understanding biometrics

Biometrics refers to the unique physical or behavioral characteristics that can be used to identify individuals. This includes features like fingerprints, iris patterns, facial recognition, and behavioral biometrics such as voice or typing patterns. Using biometrics for authentication involves a process where biometric information is scanned (like a fingerprint scan or facial recognition on a mobile device) and compared to stored data to authenticate a person's identity.
