Custom rendering of a “repeated” field from Symfony 2 in Twig

After a random guess I solved my own problem. I’ll post it here so others who might come to this question by searching also know the answer:

{% for passwordField in form.password %}
    <div class="form-field">
        {{ form_label(passwordField, null, { 'attr': {'class': 'form-label'} }) }}
        {{ form_widget(passwordField, { 'attr': {'class': 'form-input'} }) }}
    </div>
{% endfor %}
