Has anyone worked out how to integrate the Webauthn API as a passwordless login mechanism for Meteor? This would allow users to login using Windows Hello, TouchID, a Yubikey, etc. The code to register and authenticate users is fairly straightforward, but I don’t know how to let Meteor know the user is now authenticated? Any thoughts on how this could be done?
There’s a nice WebAuthn demo here: https://webauthn.io/
We use a combination of this
And Meteor’s accounts api
@rjdavid , thanks for the response. However, I don’t see any Meteor Accounts method to login the user that doesn’t require a username/password combo, an emailed token, or an oAuth integration. How did you go from successfully authenticating a user using WebAuthn to logging that user into their Meteor account?
Ah! It looks like I need to use the undocumented Accounts.registerLoginHandler
Good point that Accounts.registerLoginHandler() is not in the documentation 
Hey! I’ll add that to our backlog, Thanks for letting us know
Any updates on this? Maybe someone already implemented it in custom meteor package?
Added an issue to the core: Accounts.registerLoginHandler is still undocumented · Issue #12189 · meteor/meteor · GitHub
