Recently, the W3C finalized their Candidate Recommendation for the Web Authentication Standard, a new browser feature that allows sites to request user authentication through a standardized API.

Implementation is currently underway in Chrome, Firefox, and Edge.

Once this standard starts being implemented by sites, I'd like to be able to use KeePassXC as an Authenticator for it, so that I can store my Web Authentication private keys in the same place my existing legacy passwords are stored, and keep them synchronized across all my devices.

While it might still be too early to begin working on a concrete implementation (available documentation for the Web Authentication API is still a little sparse, outside of the standards document itself), I figured it can't hurt to start looking into this now so we're prepared when the time comes.

Would integration with the Web Authentication API be a feature worth supporting?
