We would not add an API that silently reports whether a credential is present on the current machine because that would create an inappropriate tracking vector. There is a problem that creating a credential can overwrite an existing credential. There is a [proposal](https://github.com/w3c/webauthn/issues/1637#:~:text=preventing%20unintended%20credential%20overwrites) to adopt Window's current behaviour to avoid that. (You say above that “Resident credentials have a lot of zombies”. That suggests that the [user handle](https://www.w3.org/TR/webauthn-2/#user-handle) isn't being set correctly: there should only be a single discoverable credential per (RP, user handle) on a given authenticator.) In terms of knowing whether a credential exists for signing in, there is also a [proposal](https://github.com/w3c/webauthn/issues/1637#:~:text=changes-,conditional%20ui,-Status) to integrate with autocomplete for that. -- GitHub Notification of comment by agl Please view or discuss this issue at https://github.com/w3c/webauthn/issues/1639#issuecomment-874245968 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
