Exposed username and password in javascript

[normkatz]

Wondering why you're exposing the sendgrid account username and password in javascript via the extension in the function "buildQuickForm" in class CRM_Sendgrid_Form_SendGrid in the file SendGrid.php on lines 32-35 at path sites/default/local/CRM/extensions/com.imba.sendgrid-2.0/CRM/Sendgrid/Form.

class CRM_Sendgrid_Form_SendGrid extends CRM_Core_Form {

function buildQuickForm() {
    require_once('CRM/Core/Resources.php');
    else $attr = null;

    $el = $this->add('text', 'username', ts('Username'), $attr);
    if (!$is_writable)
        $el->setSize(40);
    $el = $this->add($is_writable ? 'password' : 'text', 'password', ts('Password'), $attr);

Do you have any plans to refactor and eliminate this and use server-side credentials instead?

Is there a sendgrid component you recommend that supersedes this one?

Thanks!
