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