Is there a way where in a check through a .phtml block to see that the customer is logged in, and If so, automatically log them out - please no observers or modules.

I feel confident that I've seen a solution that talked about auto log out somewhere vaguely, but I am unable to find this.


Try this:

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$customerSession = $objectManager->create('Magento\Customer\Model\Session');

  • I read that using object manager from a .phtml isn't that great for reasons - I forget what they are. I see people warning against doing that in other answers. However, thank you for your help. Is there another solution that may use this not as directly? magento.stackexchange.com/questions/117098/… – GuitarKat Feb 28 at 14:33

In your block class:

public function __construct(
    Context $context,
    \Magento\Customer\Model\Session $customerSession
) {
    $this->customerSession = $customerSession;
public function logoutCustomer()
    $customerId = $this->customerSession->getId();
    if ($this->customerSession->isLoggedIn()) {
        return "Customer logout successfully";
    return false;

Call function in your phtml file:

<?php $block->logoutCustomer(); ?>

  • Hello there! I have a question to your solution or anyone who may have an idea about what block class means exactly. I noticed you used a block class... where would that be located? I have my phtml referenced in a .phtml - I do like how you're not using objectManager directly. – GuitarKat Feb 28 at 14:40
