I need a solution to send the OLD password of a customer who click and enter his email address in Forgot your password page. The default email template send just a link inviting the customer to reset his password at the site's page.
It is not possible to send the old password.
Recovering the old password might be userfriendly for your customers, but from a security point of view it's the best if the password can't be calculated back again and a new one will be generated. Just imagine someone retrieves access to your database - he/she could decrypt all passwords of your customers (which, might be used by them on other websites too...).
