Please try the below code in your custom extension to check if the customer login failed!

In the di.xml file of custom extension:

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\Customer\Model\AccountManagement" type="vendor\module\Model\AccountManagement" />
</config>

And add the AccountManagement.php file under the Model directory

<?php

namespace vendor\module\Model;

class AccountManagement extends \Magento\Customer\Model\AccountManagement
{
    public function authenticate($username, $password)
    {
        //Add the code below as per your requirement

        try {
            $customer = $this->customerRepository->get($username);
        } catch (NoSuchEntityException $e) {
            throw new InvalidEmailOrPasswordException(__('Invalid login or password.'));
        }

        $customerId = $customer->getId();
        if ($this->getAuthentication()->isLocked($customerId)) {
            throw new UserLockedException(__('The account is locked.'));
        }
        try {
            $this->getAuthentication()->authenticate($customerId, $password);
        } catch (InvalidEmailOrPasswordException $e) {
            throw new InvalidEmailOrPasswordException(__('Invalid login or password.'));
        }
        if ($customer->getConfirmation() && $this->isConfirmationRequired($customer)) {
            throw new EmailNotConfirmedException(__("This account isn't confirmed. Verify and try again."));
        }

        $customerModel = $this->customerFactory->create()->updateData($customer);
        $this->eventManager->dispatch(
            'customer_customer_authenticated',
            ['model' => $customerModel, 'password' => $password]
        );

        $this->eventManager->dispatch('customer_data_object_login', ['customer' => $customer]);

        return $customer;
    }

}

Hope this helps!

Magento 2 does not have any event by which you can check customer login failed. Magento login validation check from \Magento\Customer\Model\AccountManagement::authenticate for customization .

So, you want any customization then you have to work base on the method login failed. Magento login validation check from
