Practical Authentication Mechanism using PassText and OTP

Nowadays, especially with technology’s fast development, password authentication mechanism is not enough anymore to provide complete security. This paper aims to implement a strong authentication mechanism with a practical reauthentication technique that answers the research question “how to increase the security of the authentication mechanism without sacrificing convenience?” The proposed solution is a combination of a text file that the user has to modify, “PassText”, and a one-time password “OTP”. This paper is based on achieving four main solution requirements: convenience, security, cost, and speed. Our proposed solution breaks the rules of security-convenience tradeoff by providing an intelligent authentication combination that provides security and convenience at the same time.
