duo_unix - Duo two-factor authentication for Unix systems

Duo Unix with Pluggable Authentication Modules (PAM) support provides a secure and customizable method for protecting Unix and Linux logins.

Duo can be easily added to any Unix system to protect remote (SSH) or local logins with the addition of a simple pam_duo PAM module. It has been tested on Linux (RedHat, Fedora, CentOS, Debian, Ubuntu, Amazon Linux), BSD (FreeBSD, NetBSD, OpenBSD), Solaris, HP-UX, and AIX. The code is open-source and available on GitHub.
