Two-factor authentication (2FA) is a new buzzword in the information security world. Big companies that used passwords as an authentication mechanism now have started transitioning to 2FA. One form of two-factor authentication is known as one-time password (OTP). In today’s time, there is a lack of a secure multi-factor authentication platform that is also user friendly. In all the major 2FA platforms that exist today, the user has to manually enter the OTP from their phone or email. This problem is further amplified by delays in transmission of OTP via email or SMS. There has also been an increase in the number of botnets that scan large networks and try to open vulnerable ports on cloud hosting networks. An easy-to-use port security solution is not available. This research work aims to create a secure, proof-of-concept implementation of a modern and opinionated two-factor authentication system based on Near Sound Data Transfer (NSDT) technology enabling contactless secure transmission of time-based one-time password (TOTP).
