Hi

You should override prestashop to solve this problem:

if ( wrongPassWord ) {

    checkOldWay => setNewPassword

}

We did this for some of our clients after migration on store-migrations

Hi, it's a good solution.
I have had the same problem and I have solved changing directly the submit function of CustomerLoginForm.php in classes/form. (I don't know why override doesn't work)

This is the code that I have used, I leave it here for those who need it.

use PrestaShop\PrestaShop\Adapter\ServiceLocator;  /* put this at the beginning of the file */

/*then look for the function submit and replace it completely with this*/
    public function submit()
    {        
        if ($this->validate()) {
            Hook::exec('actionAuthenticationBefore');
            $oldkey = "xxxxxxxxxxxxxxxxxx_your old _COOKIE_KEY_xxxxxxxxxxxxxxxxxxxxxx";  /* change this for your old key */
            $pass_old_type = md5($oldkey . $this->getValue('password'));
            
        try {
            /** @var \PrestaShop\PrestaShop\Core\Crypto\Hashing $crypto */
            $crypto = ServiceLocator::get('\\PrestaShop\\PrestaShop\\Core\\Crypto\\Hashing');
            } catch (CoreException $e) {
                return false;
                }
                $customer = new Customer();
                $my_customer_values = $customer->getByEmail($this->getValue('email'));
                $passwordHash = $my_customer_values->passwd;
                        
            if ($pass_old_type === $passwordHash) {
                
                 $customer->passwd = $crypto->hash($my_customer_pass, _COOKIE_KEY_);
                 $ok =  Db::getInstance()->update('customer', array( 'passwd' => $customer->passwd), '`id_customer` = '.(int)$customer->id);
            }
            
            $customer = new Customer();
            $authentication = $customer->getByEmail(
               $this->getValue('email'),
               $this->getValue('password')
            );
                    
            if (isset($authentication->active) && !$authentication->active) {
                $this->errors[''][] = $this->translator->trans('Your account isn\'t available at this time, please contact us', [], 'Shop.Notifications.Error');
            } elseif (!$authentication || !$customer->id || $customer->is_guest) {
                $this->errors[''][] = $this->translator->trans('Authentication failed.', [], 'Shop.Notifications.Error');
            } else {
                $this->context->updateCustomer($customer);

                Hook::exec('actionAuthentication', ['customer' => $this->context->customer]);

                // Login information have changed, so we check if the cart rules still apply
                CartRule::autoRemoveFromCart($this->context);
                CartRule::autoAddToCart($this->context);
            }
        }

        return !$this->hasErrors();
    }

/* end of code */

This code validates the password of the client who wants to login and if it is old it becomes new and records it in the bd.

(forgive my english)
