$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
// Load customer
$customer = $objectManager->create('Magento\Customer\Model\Customer')->load(2); //2 is Customer ID

// Load customer session
$customerSession = $objectManager->create('Magento\Customer\Model\Session');

if($customerSession->isLoggedIn()) {
    echo "Customer Logged in";
    echo "customer is Not Logged in";

A better way nowadays with Magento 2 is:

protected $_customerFactory;
protected $_sessionFactory;

public function __construct(
    \Magento\Customer\Model\CustomerFactory $customerFactory,
    \Magento\Customer\Model\SessionFactory $sessionFactory,
    $this->_customerFactory = $customerFactory;
    $this->_sessionFactory = $sessionFactory;

Now lets say this is on a Magento 2 Controller, then we have the below:

public function execute()
    $customer = $this->_customerFactory->create()->load($id) //$id is the 
    customer id you want to load
    $sessionManager = $this->_sessionFactory->create();

It is always best practice to use dependency injection to retrieve either model factories or interfaces for the tool you want to use instead of getting object manager instances.


Take a look at app/code/Magento/Customer/Controller/Account/LoginPost.php

class LoginPost extends \Magento\Customer\Controller\AbstractAccount


  public function execute()
    if ($this->session->isLoggedIn() || !$this->formKeyValidator->validate($this->getRequest())) {
        /** @var \Magento\Framework\Controller\Result\Redirect $resultRedirect */
        $resultRedirect = $this->resultRedirectFactory->create();
        return $resultRedirect;

    if ($this->getRequest()->isPost()) {
        $login = $this->getRequest()->getPost('login');
        if (!empty($login['username']) && !empty($login['password'])) {
            try {
                $customer = $this->customerAccountManagement->authenticate($login['username'], $login['password']);
  • You're a wizard. How do you even find this stuff? Trying to do anything remotely "off the beaten path" with Magento and it's posts like this which provide the solutions to my problems. Thanks.
