The WiKID Strong Authentication System is a patented dual-source, software-based two-factor authentication system designed to be less expensive and more extensible than hardware tokens. The WiKID Strong Authentication Server comes as a software appliance, an ISO or in RPM format and works in conjunction with software tokens running on PCs (Windows, Mac, Linux) or wireless devices, such as the iPhone to securely deliver one-time passcodes. WiKIDs architecture allows greater extensibility and cross-enterprise two-factor authentication without requiring multiple tokens. A version of the server is available for download and evaluation.
