I wanted to confirm this is accurate as it is not very transparent from the docs, and if there are any plans to add support for this.</p>
<p dir="auto">I want to implement a passkey login using the WebAuthn API where the user does not need to provide a username/email. I understand there is a "re-authentication" workflow, but that seems designed around the hosted login pages rather than the API. Thanks!</p>

<p dir="auto">You are right. FusionAuth does not support discoverable WebAuthn passkeys. In the page you referred to, there is some verbiage that states that directly in the <em>credential.clientExtensionResults.credProps.rk</em> section.</p>
<p dir="auto"><em>'FusionAuth does not currently support discoverable credentials (sometimes referred to as "resident keys").'</em></p>
<p dir="auto">I'd recommend checking the <a href="https://github.com/FusionAuth/fusionauth-issues" rel="nofollow ugc">FusionAuth GitHub issues</a> or opening/upvoting a feature request to track progress on this.</p>
<p dir="auto">Maybe if you tell us a little more about your use case and why the user can't enter the username/email someone can help with a work around.</p>
