If you want to Magento2 Checkout shipping address autofill during checkout then you have to use Magento 2 plugin.

I have used plugin over on Class below classes for autofill checkout Shipping address:

Create after Plugin (Devbera\AutofillCheckoutAddress\Plugin\Magento\Checkout::afterMerge ) on Magento\Checkout\Block\Checkout\AttributeMerger::merge for shipping address fields autofill up.

Step1:Define Plugin classes:

First Create di.xml at app/code/{VendorName}/{ModuleName}/etc/frontent where we are define the plugin classes.

Code

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Checkout\Block\Checkout\AttributeMerger">
        <plugin disabled="false" name="checking_shipping_address_auto_full"
                sortOrder="10" type="{VendorName}\{ModuleName}\Plugin\Magento\Checkout\AttributeMergerPlugin"/>
    </type>
    <type name="Magento\Checkout\Model\DefaultConfigProvider">
        <plugin disabled="false" name="checking_email_auto_full" sortOrder="10"
                type="{VendorName}\{ModuleName}\Plugin\Magento\Checkout\Model\DefaultConfigProviderPlugin"/>
    </type>
</config>

Step2: Declare plugin class

Create First plugin class AttributeMergerPlugin.php at app/code/{VendorName}/{ModuleName}/Plugin/Magento/Checkout/

Second plugin class which will auto fill email id for NON _login customer

Create seocnf plugin class DefaultConfigProviderPlugin.php at app/code/{VendorName}/{ModuleName}/Plugin/Magento/Checkout/Modelt/

<?php
/**
 * @category   Devbera
 * @package    Devbera_AutofillCheckoutAddress
 * @author     Amit Bera <[email protected]>
 * @website    http://www.amitbera.com
 * @license    http://opensource.org/licenses/osl-3.0.php  Open Software License (OSL 3.0)
 */

namespace {VendorName}\{ModuleName}\Plugin\Magento\Checkout\Model;

use Magento\Framework\App\Http\Context as HttpContext;
use Magento\Customer\Model\Context as CustomerContext;

class DefaultConfigProviderPlugin
{
    /**
     * @var HttpContext
     */
    private $httpContext;

    public function __construct(
        HttpContext $httpContext
    ) {
        $this->httpContext = $httpContext;
    }

    public function afterGetConfig(
        \Magento\Checkout\Model\DefaultConfigProvider $subject,
        $result
    ) {
        if (!$this->isCustomerLoggedIn() && is_array($result)) {
            $result['validatedEmailValue'] = '[email protected]';
        }
        return $result;
    }
    /**
     * Check if customer is logged in
     *
     * @return bool
     * @codeCoverageIgnore
     */
    private function isCustomerLoggedIn()
    {
        return (bool)$this->httpContext->getValue(CustomerContext::CONTEXT_AUTH);
    }
}

Disabled Autofill fields

If you want to disallow this autofill fields from editable for the customer then you have to add below code

$fields[$attributecode]['disabled'] = true; 

after autofill value set like you want disable first name field disable for customer after auto fill then add below code:

case "firstname":
    $fields[$attributeCode]['value'] = 'John';
    // Disable first  name field 
    $fields[$attributecode]['disabled'] = true; 		
    break;
case "lastname":
    $fields[$attributeCode]['value'] = 'Deo';
    break

Autofills Street field

Here, you may be seen that I have used different condition for the street because of this field is multiline code field. By default Magento street field is two lines, then you can use below code

 $fields[$attributecode]['children'][1]['value'] = 'Mayer road';

Here , at associated array value is 1 ( [‘children’][1]) as its line no is 2.
