Discuss briefly the pros and cons of biometric authentication

What will be an ideal response?

Biometric authentication uses personal physical characteristics such as fingerprints, facial features, and retinal scans to authenticate users. It provides a strong authentication, but the required equipment is expensive. Users often resist biometric identification because they feel it is invasive. Biometric authentication is in the early stages of adoption. Due to its strength, it likely will see increased usage in the future. It is also likely that legislators will pass laws governing the use, storage, and protection requirements for biometric data.
