Initiative for Open Authentication (OATH) is an industry-wide collaboration to develop an open reference architecture using open standards for adoption of strong authentication.

OATH is comprised of industry leaders working with other standards groups toward the propagation of ubiquitous strong authentication, enabling eBusiness and giving customers the confidence to conduct secure commerce and communication online. An OATH ecosystem consists of devices, chip sets, platforms, applications, integrators, and customers, all working together in a strongly authenticated, highly secure environment.
