Exam CAS-004 topic 1 question 401 discussion

Another way to look at this question is what the fore mentioned technologies have in common.

The technology that would benefit the most from the use of biometric readers, proximity badge entry systems, and hardware security tokens for accessing various environments and data entry systems is **D. Passwordless authentication**. Passwordless authentication aims to provide secure access to systems and data without relying on traditional passwords. Biometric readers, proximity badge entry systems, and hardware security tokens are all components of passwordless authentication systems that enhance security by using something the user has (such as a hardware token) or something the user is (such as biometric data) for authentication, rather than relying solely on something the user knows (like a password). Deep learning (A), machine learning (B), nanotechnology (C), and biometric impersonation (E) are not directly related to the specific authentication methods mentioned in the question.
