Abstract
Systems, methods and articles of manufacture for evaluating a password policy are disclosed. The password evaluation system receives password policy data regarding a password policy, including a password constraint. The system analyzes the password policy data to determine a usability index and a password strength index for the password policy, and also determines a usability index and password strength index for a plurality of modified password policies having password constraints different from the password policy. The system then provides a graphical representation of the usability index and the password strength for the password policy and the modified password policies, thereby allowing a password designer to optimize the tradeoffs between usability and security of a password policy.
