WebAuthn integration#22
Conversation
|
HI Adam, Since BobPay is meant to be sample code for a payment app, I would rather have two versions. The current one at /pay, and one that supports authn at /pay-authn for example. It leads to code duplication, but at least people will know where to look. It shouldn't be too much work to duplicate the registration links and functions. Let me know if that's ok with you. |
|
@madmath How would the payment handler know to open |
|
Sorry if I was unclear, I meant that there would be two payment apps on bobpay.xyz. One at /pay and the other at /pay-authn, installable separately and usable separately too. |

Here we should feature-detect for web authentication functionality to avoid breaking the demo for those who don't have it turned on:
if (window.WebAuthnTransacttion) {
var authn = new WebAuthnTransaction();
// Web Authentication flow.
} else {
var paymentAppResponse = {
// The existing flow without Web Authentication.
}

Let's put the WebAuthn code into a <div id="webauthn"> and show it only if Web Authentication is enabled.
<div id="webauthn" style="display: none;">
...
</div>
<script>
if (window.WebAuthnTransaction) {
document.getElementById('webauthn').style.display = 'block';
}
</script>

@madmath Do you think a single payment app would be more manageable with feature-detection for Web Authentication? |
|
Sorry to disappoint, I don't. The goal for BobPay is to provide the canonical sample for Payment Handler, and in its vanilla form I don't think we should include other code that conflate it with WebAuthn, and make the example less understandable. What's the problem with installing either one of two apps?
Duplicate the "pay" folder to "pay-authn" and provide two links at the bottom of BobPay.xyz so that people can choose which they want to register. |
|
OK, let's go with two separate apps, @madmath. |
|
In that case should I just maintain my fork separately? Makes maintenance easier (i.e. - merge upstream changes) and I can add you guys as contributors if you need any control. |
|
@apowers313 If maintaining a fork is easier for you, go for it. We don't require control. |

Two major updates:
Two major flaws to be solved:
Caveat: WebAuthn isn't currently working on my phone due to SafetyNet issues, so I haven't been able to test this out on a mobile device. Development was done with Firefox on the desktop, and the arguments passed to WebAuthn are probably wrong for Chrome. I'll update my FIDO repo with the correct WebAuthn functionality once I have a working phone.
