Multifactor Authentication

Authentication can be accomplished with one factor, two factors, or multiple factors. Which one is the weakest level of authentication and which is the most secure and why? When would a more secure system be required? Be able to explain these multifactor authentication methods: password protection, token presence, voice biometrics, facial recognition, ocular-based methodology, hand geometry, vein recognition, fingerprint scanner, thermal image recognition, and geographical location. What are some challenges of multiple factor authentication when using biometrics? There is a lot of interesting information covered in this article that you do not need to memorize, but that you should be aware of.

3. MFA Operation Challenges

An integration of novel solutions has always been a major challenge for both developers and managers. The key challenges are presented in Figure 3. In the first place, user acceptance is a critical aspect for the adoption of strong identity and multi-factor authentication. While adopting and deploying MFA solutions, it is required to follow a careful and thorough approach – where most challenges arise from opportunities and potential benefits.
