Password-based security has become a liability due to sophisticated phishing attacks and challenges faced by users to create and manage numerous passwords. The centralized storage of millions of user credentials including passwords within the cloud or a website server provides a single point of attack for hackers, which can greatly increase the cost of a single data breach. Online attacks like Man-in-the-Middle (MitM) and Man-in-the-Browser (MitB) can pose a substantial threat to online authentication by secretly modifying the communication between the user and server.
