            Bug ID: 246339
           Summary: [WebAuthn]
                    window.PublicKeyCredential.isUserVerifyingPlatformAuth
                    enticatorAvailable set to False for carnival.com |
                    Safari IOS 16.1
           Product: WebKit
           Version: Safari 16
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit API

While trying of using WebAuthn on carnival.com with IOS 16.1 (beta 4) and mobile Safari, we discovered that the PublicKeyCredential.isUserVerifyingPlatformAuthenticatorAvailable flag was set to false for unknown reasons. From the source code of Webkit, it appears that Webkit is blocking the use of Webauthn for a number of domains which are not publicly shared. The issue occurs only on carnival.com.

As far as I am aware, this is a bug because it works perfectly on IOS 16.0 with Safari (as passkeys) on the domain carnival.com.
