How can biometric authentication improve user experience and trust?

What is biometric authentication and why is it important?

What is Biometric Authentication?

Biometric Authentication is a security process that verifies an individual's identity based on their unique biological characteristics. These characteristics are distinct and difficult to replicate, making them highly reliable for authentication purposes. Common biometric identifiers include:

1.      Fingerprints: Unique patterns of ridges and valleys on the fingers.

2.      Facial Recognition: Analysis of facial features such as the distance between eyes, nose, mouth, and jawline.

3.      Iris/Retina Scans: Patterns in the colored ring of the eye (iris) or the unique pattern of blood vessels in the retina.

4.      Voice Recognition: Vocal characteristics and patterns.

5.      Hand Geometry: Shape and size of the hand and fingers.

6.      Behavioral Biometrics: Patterns in how an individual types, walks, or uses a device.
