Our two-factor authentication server is available as a Linux package for RedHat, Centos, Fedora & Ubuntu; an ISO for virtual appliances (or bare metal!); a Virtualbox image. Please see our installation documentation. You must install both the Server and the Utilities packages. Please verify the provided MD5Sums.
Recommended: Download the Virtual Appliance ISO 4.0.1-b1906 (d91527325a140535eb35318f8dc1bac6). The ISO is a complete operating system with all the needed packages. It is based on Centos 6, but no LInux knowledge is required. Use this to build your virtual (or real) two-factor authentication appliance. It is 64 bit.
Download DEBs: WiKID Server Enterpise 4.0.1-b1905 (a725fe2b1ed559b5af7c46a8eda68b76) and WiKID Utilities (1535104828a401420f30d1efae5f233e). A quirk of the build system put this at 1905. It's the same software.

After downloading the WiKID two-factor authentication server, please see the Installation documentation.
Download the Software Token Clients for Windows, Mac, Linux, Blackberry, Android, iPhone, Windows Mobile and J2ME devices. Unlike most software tokens, WiKID uses public key encryption to securely deliver one-time passcodes. We do not keep a copy of your seed. It's a better way to do two-factor auth.
We have a simple API and packages for Python, Ruby, Java, C# and PHP to make it easy to add two-factor authentication to your custom application.
