Most companies are now equipped with an Enterprise WIFI from Cisco or similar network device vendors. Wifi provides over-the-air bridging to your corporate infrastructure and also needs to be secured accordingly.
OpenOTP for Wifi provides both single factor and multi-factor authentication over the common Wifi standards. The supported authentication protocols are Wifi Enterprise over RADIUS with EAP-GTC (commonly used by Cisco) and EAP-TTLS-PAP. Any other Wifi protocols is not compatible with OpenOTP and OTP technologies in general.
