The success of the FIDO Alliance ecosystem is predicated upon user trust, with the goal of preserving users’ privacy while providing strong authentication to online services. This paper describes the privacy-preserving principles that are a core part of the FIDO Alliance’s technologies, and explains how they reinforce the FIDO Alliance’s approach to strong authentication. 

These Privacy Principles reflect the FIDO Alliance’s unambiguously strong commitment to protecting our users’ privacy. The comprehensive technical mechanisms that pervade FIDO’s specifications provide the foundation that makes the FIDO standards as privacy-protecting as they are secure.
