Misspelled word "authenticator" here.

Thank you for fixing that typo!

This little check and assignment is repeated so many times it might be nice as a static function:

static void createMalformedCredentialErrorIfNecessary(NSError **error)

> Source/WebKit/UIProcess/API/Cocoa/_WKWebAuthenticationPanel.mm:488
> +            *error = [NSError errorWithDomain:WKErrorDomain code:WKErrorDuplicateCredential userInfo:nil];

... or, perhaps a helper that takes the WKError type:

static void createNSErrorFromWKErrorIfNecessary(NSError **error, WKErrorCode errorCode)
{
    if (error)
         *error = [NSError errorWithDomain:WKErrorDomain code: errorCode userInfo:nil];
}
