Reset password at first login

I’ve imported the users of my previous ecommerce site (CMS: Joomla + Virtuemart) in WordPress (with WooCommerce).
It wasn’t possible to import the passwords.
Is there the possibility, if the user try to log in with the email address (and with the old password), that WordPress asks for a password reset? It should happen only at the first login attempt.
I’ve searched for a plugin but I’ve found nothing.
Thanks a lot in advance.
Wordpress 4.5.2
WooCommerce 2.4.13
