Summary

Adds an 'opt-out' flow to Secure Payment Confirmation. When the (optional) input flag is set, the SPC UXes will render an 'opt-out' link of some sort that the user can interact with to indicate to the relying party that they wish to be opted out.

SPC feature is a combination of WebAuthn and PaymentRequest APIs.

Activation

To take advantage of this feature, developers have to specify a new optional API parameter `showOptOut: true`.

Normal devtools javascript debugging capabilities should suffice.

Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?

No

SPC is currently launched only on Mac, Windows, and Android. This opt-out feature also exists only on Mac, Windows, and Android.

Is this feature fully tested by web-platform-tests?

Yes
