This feature has been removed. Original summary: The Web Authentication API (Chrome 65 and later) lets web applications authenticate users via FIDO-defined U2F and CTAP2 devices. The implementation supports certain platform authenticators (like TouchID) and external devices communicating over USB. This feature adds supports for communicating with external devices over BLE, including a UI to guide users in pairing and using their devices for two factor authentication (for Mac and ChromeOS).


Supporting BLE authenticators had significant reliability challenges and the we did not have important enough use cases to justify the development and maintenance burden that this feature would incur. Accordingly, the code for this was removed in early 2020.
