Tooltips are used to provide additional information especially about clarifying the input requirement or explaining specific options.

Checkout errors are reduced as the user gets the required information. 

Let’s find out how you can add a tooltip in the checkout shipping field in Magento 2.

    <type name="Magento\Checkout\Block\Checkout\LayoutProcessor">
        <plugin name="Custom_Checkout" type="Vendor\Extension\Plugin\LayoutProcessor" sortOrder="100"/>
    </type> 
</config>

Step 2: Create a LayoutProcessor.php in path given below.

{magento_root}}\app\code\Vendor\Extension\Plugin\LayoutProcessor.php

namespace Vendor\Extension\Plugin;

class LayoutProcessor
{
    public function afterProcess(
        \Magento\Checkout\Block\Checkout\LayoutProcessor $subject,
        array $jsLayout
    ) {
        $jsLayout['components']['checkout']['children']['steps']['children']['shipping-step']['children']
    ['shippingAddress']['children']['shipping-address-fieldset']['children']['lastname']['tooltip']['description'] = "Enter your last name here.";
        return $jsLayout;
