[SGVLUG] One Time Password Authentification

[James McDuffie]

The January 2013 issues of Linux journal has a neat article about one
time passwords. It is a two factor authentication method you can install
yourself really easily. The software gives you a page of one time use
passwords that together with a secret prefix allows you to log into your
system from untrusted machines.
