Persona, Incode and Veratad are the latest companies to join the network of platforms, identity providers and trust infrastructure firms that have come on board with OpenAge’s FIDO passkey-based its age-verification credential, the AgeKey. In OpenAge’s case, the initial verification from a participating provider will work as an age signal across services that accept AgeKeys. The system adheres to open standards and data minimization principles, notably in employing a double-blind model for age checks. Reusable age credentials allow individuals to verify their age once, using methods such as facial age estimation then reuse that verification across channels. Veratad brings the orchestration side to the mix.
