WebAuthn enables online services to use FIDO Authentication through a standard web API that can be built into browsers and related web platform infrastructure
It is a collaborative effort based on specifications initially submitted by FIDO Alliance to the W3C and then iterated and finalized by the broader FIDO and W3C communities
WebAuthn was designated an official web standard in March 2019
It is currently supported in Windows 10 and Android platforms, and Google Chrome, Mozilla Firefox, Microsoft Edge and Apple Safari web browsers.
