‘Physical Tokens’ vs ‘Onetime Password Messaging’


Question: Which proposition do you think is better as the second factor of 2-factor authentications?

Answer: All depend on where you see the better balance between security and convenience for each use case.

We could see a merit of physical tokens or hardware keys as against OTP messaging that is relatively more vulnerable in the online environment, but we could also see its demerit ; When we have dozens of accounts to protect, would we have to carry around a big bunch of hardware keys which could physically catch a quick eye of bad guys or would we have to re-use one or a few hardware keys across many accounts, physically creating a single point of failure?

In order to overcome this conflict, we came up with our own proposition of 2-channel/2-factor authentication for achieving an optimal balance between security and convenience at a higher level, which was implemented for a corporate network 6 years ago and is still running.

Expanded Password System to Complement FIDO2

2 is larger than 1 but is not necessarily stronger than 1, as two children could be overwhelmed by a grown-up. For a two-factor authentication to be really reliable, each factor should be reasonably secure and usable enough. On the other hand, ‘password-less’ authentication, however attractive it might sound, would only benefit bad guys as examined in the link page - https://www.linkedin.com/pulse/removal-passwords-its-security-effect-hitoshi-kokumai/ People who offer a token as 'a factor' of two factor authentication schemes could all be viewed as our potential down-stream partners. Among them are the people who offer FIDO2-compatible solutions. Put together, we could come up with the two-factor authentications that are much more reliable than otherwise.

Quest for Global Ubiquity

We wish to make our Expanded Password System solutions readily available to all the global citizens: rich and poor, young and old, healthy and disabled, literate and illiterate, in peace and in disaster. For achieving such global ubiquity, we will need more and more research into such diverse disciplines as psychology, sociology, behavioural economics and brain science in addition to cryptography, safe coding and other security technologies. Your shout would be welcomed if you happen to know researchers who may be interested to include the issue of ‘identity assurance by our own VOLITION and MEMORY’ in their study subjects or if you yourself are interested to join us. We will shortly launch the global operation of promoting Expanded Password System from our headquarters set up in UK and this research program, which should naturally be international, is to play a significant role in it. Linked is my article posted 6 years ago, which might indicate an aspect of what we

Biometrics for Increasing and Decreasing Security

https://www.fedscoop.com/phone-cases-security-air-force-disa/ It could be a correct use of biometrics for increasing security if biometrics is used for continuously monitoring the user's voice and behaviors to detect when a bad guy has grabbed the logged-in device from the user. Demand the user's password afresh, and the bad guy could be turned away as discussed here - "Anything used correctly is useful and so are UV, disinfectant and biometrics." https://www.linkedin.com/posts/hitoshikokumai_digital-identity-anything-used-correctly-activity-6663264695664934913-S2FS It could be a wrong use of biometrics for decreasing security if biometrics is used as a second authenticator along with a default password as examined here - "Early models of smartphones were safer than newer models - How come?" https://www.linkedin.com/pulse/early-models-smartphones-were-safer-than-newer-how-come-kokumai Windows Hello for payment authentication would be fi
