Apparently they intend to build native payment extensions for FIDO into the browser.

Hi Payments WG,

I'd like to get your feedback on the proposed WebAuthn to Pay (aka Secure Payment Confirmation) pilot [1]. The goal of this pilot is to prototype an enhancement of the 3DS step-up flow (direct user authentication with the issuer during checkout using WebAuthn without redirect) and evaluate the user friction and conversion impact of such a flow.

The finalized UX mocks [2] were discussed at today's WebAuthn/WPWG Joint Task Force call [3].

For the WPWG call this coming Thursday, July 23rd, I'll do a walk-through of the sequence diagrams [4][5]. I look forward to your feedback.

If you have any questions, please reach out to myself and my collaborators on this proposal: Benjamin Tidor (btidor at stripe.com <mailto:btidor at stripe.com>), and Adrian Hope-Bailie (adrian at coil.com <mailto:adrian at coil.com>).

Danyao, on behalf of the WebAuthn to Pay collaborators
