Abstract
Authentication mechanisms face various online threats, such as malware programs and phishing scams, which challenge the existing authentication mechanisms’ security and usability. Authentication mechanisms with poor usability may easily be exploited by attackers and result in severe security risks. In order to guarantee the design quality of authentication mechanisms, we propose a set of usability metrics. With the help of the proposed usability metrics, software developers and security and usability experts will be able to evaluate and measure usability and security quality of authentication mechanisms.
