Document WebAuthN, currently behind a feature flag
Problem to solve
We've implemented WebAuthN, a FIDO2 standard, that goes one step beyond the U2F features associated with FIDO.
We have not documented this new feature.
Further details
We now have some related UI text, !41641 (comment 420039481)
Proposal
Document our support for WebAuthN, possibly in a page parallel to our 2FA support.
Include info on how our readers can activate the related feature flag.
