One Time Passwords in Everything (OPIE)

OPIE is a freely redistributable kit that will drop into most *IX systems and replace your login and FTP daemon with versions that use OTP for user authentication. It also includes an OTP generator and a library to make it easy to add OTP authentication to existing clients and servers.

The current version of OPIE is 2.4.1-test1. I also distribute a number of contributed programs and have made a few patches to make existing programs use OTP through the OPIE library.

I'm not wearing my OPIE hat much anymore. A new release is planned, but is progressing very slowly due to lack of time to spend on it right now. I also plan to cut bug-fix releases periodically. Contributed code that changes OPIE for the better is always welcome.
