Simplistic models of user and attacker behaviors have led the research community to emphasize the wrong threats. Authentication is a classification problem amenable to machine learning, with many signals in addition to the password available to largeWeb services. Passwords will continue as a useful signal for the foreseeable future, where the goal is not impregnable security but reducing harm at acceptable cost.}, publisher = {ACM - Association for Computing Machinery}, url = {http://approjects.co.za/?big=en-us/research/publication/passwords-and-the-evolution-of-imperfect-authentication/}, journal = {Communications of ACM}, edition = {Communications of ACM}, }
