It seems like addHidden() must be provided by classes using this trait. How about adding it as abstract method to this trait?

        $this->getElement('recaptchaResponse')->setId('recaptchaResponse');

It seems like getElement() must be provided by classes using this trait. How about adding it as abstract method to this trait?

        $resp = GoogleRecaptcha::getManager()->verify($_POST['recaptchaResponse']);
        if (!$resp->isSuccess()) {
            $errors = $resp->getErrorCodes();

The assignment to $errors is dead and can be removed.

            $this->addError("Eroare validare email. Va rugam sa mai incercati!");
