OTPW is a one-time password authentication module for POSIX systems. Its security concept is optimized for users who prefer printed paper password lists over portable electronics. In this mode of operation, it provides better protection against some attacks than other schemes (e.g. S/KEY). It provides a library that can be linked with any application that performs interactive logins. A PAM wrapper is included for simple installation under Linux.
