Can browser support frictionless flow without fingerprinting?

[ianbjacobs]

3DS supports no-friction flows and merchants may even accept a liability shift in order to have zero friction flows. Risk engines today fingerprint the browser and determine whether a frictionless flow suffices. Changes in browsers are (by design) going to make the fingerprinting more difficult.

WebAuthn supports low-friction, but not no-friction flows.

What browser capabilities could support no-friction flows without adding to the fingerprinting surface?
