Identity Solution

ZenKey is a transformative technology and network-based identity solution that relies on unique attributes from both the user’s device and wireless carrier network. It gives developers an easily integratable OpenID environment for user authentication and authorization, as well as for fraud detection and prevention.

To learn more, explore our demos, Quickstart Videos, Developer Playground and the ZenKey Portal.
