The World Wide Web Consortium (W3C) and the FIDO Alliance announced the Web Authentication (WebAuthn) specification is now an official web standard.
WebAuthn is a browser/platform standard for simpler and stronger authentication. It is already supported in Windows 10, Android, and Google Chrome, Mozilla Firefox, Microsoft Edge and Apple Safari (preview) Web browsers.
WebAuthn allows users to log into their internet accounts using their preferred device. Web services and apps can — and should—turn on this functionality to give their users the option to log in more easily via biometrics, mobile devices and/or FIDO security keys, and with much higher security over passwords alone.
