I tried out registering via. FIDO2 using TouchID on my MacBook. Now the username I entered shows up when logging in under "saved accounts". Now I wan't to remove the account.
But how can I delete the WebAuthN credentials from my Mac-Device? There's no entry in "Keychain Access", where one could expect it, nor could I find anything in Safari's preferences.
Unlike iOS, clearing all website data does not clear credentials (which is probably a good thing).
