I need to be able to "intercept" in a way the plain text password to clone the registered user from a D9 site over to a D7 site via API. Alternatively if anyone knows a way to just migrate a D9 encrypted password to a D7, that would be helpful as well.

I've tried using the hook presave but the password in the user object is still already encrypted and if I pass that over to a D7 site it would not work in D7.

The general thing I'm trying to accomplish is cloning a D9 user upon registration over to a D7 legacy site via an API endpoint on D7.

Any thoughts on how this can be accomplished? Appreciate any ideas. Thanks!

Was ultimately able to solved this myself. Using form alter hook and adding to submit actions with a function then getting the value from form state.

function mymodule_my_submit($form, &forms_state) {
 /* plain text password we wanted to get on submission */
$pass = $form_state->getValue('pass');
//do whatever with it
}
function mymodule_form_alter(&$form, 
  Drupal\Core\Form\FormStateInterface $form_state, $form_id) {
 if($form_id == 'user_register_form') { 
  $form['actions']['submit']["#submit"][] = "mymodule_my_submit";
 }
}
