https://webauthn.io Conditional Popup never enabled for Chromium Browsers on Linux

[wparad]

As far as I can tell this library supports the https://webauthn.io/ site. And on that site, for Desktop + Chromium browsers, the conditional UI (while officially supported) by the Chromium browsers, never actually triggers.

I don't know where this discussion/issue should be started, but this feel unexpected. I specifically don't think it's a problem with SimpleWebAuthn, but rather something broken in Chromium :(

FWIW, I do get the conditional UI message:

{
  "challenge": "08ePuCBHWXR9a_4L6-SJa-XwaFbWwZgJ3IeyzZloJJev_B188L2FvfRCXA20YmAnMlFAT8BHMpBF6kVJ87Kvsg",
  "timeout": 60000,
  "rpId": "webauthn.io",
  "allowCredentials": [],
  "userVerification": "preferred",
  "hints": []
}

@wparad Hmm, interesting. What OS and browser(s) versions specifically are you not seeing the conditional UI appear?

[wparad]

For context on firefox (why does sometimes it popup the native firefox one and sometimes bitwarden, is a completely different issue)

Okay, then if you're getting conditional UI in Firefox it's definitely pointing towards a more simple "Chromium browsers just don't support conditional UI on Linux." And the way to improve that is to complain to the Chromium project via bug report. Though I wouldn't be surprised if there aren't already several such reports for how many people use Linux these days.

The thing is:

// returns true;
const isConditionalMediationAvailable =
  await window.PublicKeyCredential?.isConditionalMediationAvailable?.();

I can absolutely "complain to the Chromium project", though I have no hope, do you know where the most appropriate place to file bug reports is off the top of your head?

https://issues.chromium.org is the best place. Take a look first, someone might have already submitted an issue about this. But if not then definitely report a bug.

Awesome. FYI: https://issues.chromium.org/issues/485997705
