OpenOTP™ Authentication Server

OpenOTP can be installed on any Linux box (a virtual or real server). The Linux platform has been chosen for its robustness, security and maintenaibility.

OpenOTP provides the highest level of functionality available in the sector. Yet our engineers designed it focussing on high security, performance, simplicity and intuitivity. As a result, OpenOTP is the only solution at this level of functionality, that is being successfully installed and integrated by hundreds of companies without requiring any additional assistance.

Our WebADM management software provides the most advanced centralized Web interface for managing your security applications, authentication policies, users, groups and domains. All the configuration and management relies on WebADM and we also designed it for maximum ease of use and intuitivity to abstract the software complexity.
