ZenKey is a secure bridge between your users and the apps and services you provide. A joint undertaking of the three major US wireless carriers — AT&T, Verizon, and T-Mobile — ZenKey leverages encryption technologies in a user's mobile phone and mobile network. The platform packages multiple factors of authentication into a streamlined experience for app and website providers, taking advantage of the unique capabilities and insights of the wireless carriers. It then applies those capabilities to provide an easy and secure way to register, login, and perform other types of authorizations within apps and services. The result for you is a better user experience and a more secure link to users.
