Multifactor Authentication: Protecting Privacy in the Digital World

Abstract: In today’s world, digitalization decisively penetrates all the sides of the modern society. One of the key enablers to maintain this process secure is authentication. With the rapid evolution of wireless communication technology, user authentication is essential to ensure the security of wireless communication technology. It assists humans to interact with everything by enabling services that are faster, user-friendly and reliable for authentication. As from conducted surveys, a common user may have multiple online accounts which requires passwords. As an evolution in wireless communication, the user authentication plays an important role. In the process of authentication, passwords plays an important role. Importance of MFA ensures the user’s account does not get easily attacked by the attackers and also ensures that the sensitive information of the user remains safe. The objective of the system outcome is to enhance the current login authentication system. It provides solutions for making password breaking more difficult as well as convinces users to create passwords that are hard to break. This research delves into the effectiveness of MFA in diverse contexts, including its role in preventing phishing attacks, enhancing security, and adapting to emerging threats. MFA goes beyond conventional password protection, requiring users to authenticate through a combination of knowledge-based factors (Passwords, Pins), possession- based factors(Tokens, Smart-phones), and inherence-based factors(Bio-metrics). This paper explores the concept of MFA, which means combining the various types of authentication factors to enhance user security.
