How to enforce strong passwords on Protected Content registration

Is there a way to enforce strong passwords on the registration form for Protected Content?

I am using Protected Content Mojo for a custom registration form, but it adds its fields to the standard registration form. That leaves the password field untouched.

I can enforce strong passwords through either iThemes Security or Wordfence, but that doesn't seem to affect the Protected Content registration form.

Ideas?
