Re: [webauthn] Cross-origin credential creation in iframes (#1656)

I don't think any multi-party transaction has been proposed here. The proposal is not to allow site A (merchant) to register credentials on behalf of site B (payment provider), rather that site A may embed site B in an iframe, in which site B may register credentials for site B. Communication between the user and site B will be direct and not pass through site A on the way (i.e., public keys and identifiers will not be exposed to site A), and site B is in full control of the registration ceremony just like it would be with a full page redirect.

(I don't have a strong opinion either in favor or against, just trying to clear up what looks to me like a misconception.)
