Security concerns are rising today in all domains, such as banks, governments, medical assistance, military organizations, etc. Several solutions have been proposed but security loopholes and user flexibility still remain a big question. The past decade has seen a growing interest in replacing username-password authentication with new methods. On the other hand, there is a tremendous growth in web-based applications. Two factors are considered key elements in the usage of password authentication: usability and security. The authentication systems based on One-Time-Passwords (OTPs) are the most commonly used. In this paper, various OTP generation mechanisms have been reviewed and a novel OTP generation method has been presented. The OTP produced from the system is user-friendly as well as secure since it is a 6-digit OTP generated using RIPEMD160.
