       // $this->data['User']['password'] = Security::hash($this->data['User']['pwd'], 'sha1', true);
      
        if (!empty($this->data[$this->alias]['pwd'])) {                 // hashing password with sha1 and cake salt
        $this->data[$this->alias]['password'] = AuthComponent::password($this->data[$this->alias]['pwd']);
   
        }
    return true;
    }



In view

<?php echo $this->Form->input('oldpwd', array('type' => 'password','label' => '', 'class' => 'my-text-field-gen-11')); ?>

<?php echo $this->Form->input('pwd', array('type' => 'password','label' => '', 'class' => 'my-text-field-gen-11')); ?>

<?php echo $this->Form->input('password2', array('type' => 'password', 'label' => '','class' => 'my-text-field-gen-11')); ?>
