The authors present a usability study of two recent password manager proposals: PwdHash and Password Multiplier. Both papers considered usability issues in greater than typical detail, the former briefly reporting on a small usability study; both also provided implementations for download. Their paper involving 26 users found that both proposals suffer from major usability problems. Some of these are not \"Simply\" usability issues, but rather lead directly to security exposures. Not surprisingly, they found the most significant problems arose from users having inaccurate or incomplete mental models of the software.
