I need plain text password in my plugin

I want to use encrypted password to store in the remote database of the protected script but at the same time I also need a plain text password to define a MySQL user at the subscription activation time.

Here is a portion of my plugin:

PHP:

public function getPasswordFormat()
    {
        return SavedPassTable::PASSWORD_CRYPT;
    }
 
    public function onSubscriptionAdded(Am_Event $event){
        $user = $event->getUser();
        // 1. Check if user exists in MySQL
        if ($this->getPACS()->checkIfUserExists($user->login)) {
            // 2. If exists update the password
            $this->getPACS()->changePasswordDb($user->login, $pass);
        }
        else {
            // 3. If not exists create it
            $pass = $this->getDi()->savedPassTable->findSaved($user, SavedPassTable::PASSWORD_PLAIN);
            $this->getPACS()->createDbLogin($user->login, $pass);
        }
    }

The code functions except that in my hooked function I end up with an encrypted password not a plain one...

So I got the plain password in my remote DB table by using this script

PHP:

    public function getPasswordFormat()
    {
        return SavedPassTable::PASSWORD_PLAIN;
    }
 
    public function onSubscriptionAdded(Am_Event $event){
        $user = $event->getUser();
        $pass = $this->getDi()->savedPassTable->findSaved($user, SavedPassTable::PASSWORD_PLAIN);
        //$pass = $user->pass;
        // 1. Check if user exists in MySQL
        if ($this->getPACS()->checkIfUserExists($user->login)) {
            // 2. If exists update the password
            $this->getPACS()->changePasswordDb($user->login, $pass);
        }
        else {
            // 3. If not exists create it
            $this->getPACS()->createDbLogin($user->login, $pass);
        }
    }

But during the event when I try to access the plain password in the second function I end up with something scrambled. I understand the $user->pass in WordPress format is not plain text either. Do I have any chance to use a plain text password except for transitory times when the user actually submits it (at registration or login)?

Or maybe I am wrong somewhere?

Apparently this is solving my issue

PHP:

$pass = $this->getDi()->savedPassTable->findSaved($user, SavedPassTable::PASSWORD_PLAIN)->pass;
