Summary Support the attestationFormats field from WebAuthn L3. WebAuthn L3 supports a site expressing an ordered preference for credential attestation formats in the new attestationFormats field[1]. We plan on running an origin trial for this new field to allow some interested sites to experiment with this field on the one OS that currently supports it (Android). At the end, we'll gauge whether it has sufficient utility to support on an ongoing basis. Blink componentBlink>WebAuthentication <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EWebAuthentication> TAG reviewNone — this one extra field is one of many passed in WebAuthn from a browser to passkey providers and doesn't represent any meaningful change in design. Risks Interoperability and Compatibility No risks in general. Users of this field trial will have to keep in mind that it'll expire, but this is true of all trials. *Gecko*: No signal *WebKit*: No signal *Web developers*: No signals *Other signals*: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? No Goals for experimentation To let a handful of interested sites experiment with this functionality without having to support it ~forever in the broad Web Platform. At the end of the trial we'll consider whether full support is warranted. Ongoing technical constraints None Debuggability The usual tricks for inspecting WebAuthn requests still work, but much of the logic is implemented by the user's chosen passkey provider. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?No, because it can only be supported in cases where the underlying passkey provider infrastructure supports this field, which is currently only true on Android. Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?No. If we decide in the future to ship this feature fully we'll add WebDriver support and flesh out the testing. But the need for integration into a virtual authenticator for testing makes this a non-trivial amount of work.
