I have tried everything as mentioned in the above blog but still Same Site cookie issue is not getting resolved.


Re: Magento 2.4.3 Same Site Cookie None Issue

Hello @sagar_gopale 


We have faced the same issue due to chrome version.

You can refer below custom code for resolve.

You can try setting the samesite=None by following steps..

file : etc/frontend/di.xml

<?xml version="1.0"?>
<config xmlns:xsi="" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Framework\View\Element\Js\Cookie">
        <plugin name="afterGetPath" type="namespace\module\Plugin\View\Element\Js\ManagePath" sortOrder="10"/>

file : Plugin/View/Element/Js/ManagePath.php

namespace namespace\module\Plugin\View\Element\Js;

use Magento\Framework\View\Element\Js\Cookie;

class ManagePath
    public function afterGetPath(\Magento\Framework\View\Element\Js\Cookie $subject, $path)
        if (preg_match('/SameSite/', $path)) {
             $path_array = explode(';', $path);
             $path = $path_array[0];
        return $path;


file : etc/di.xml

<?xml version="1.0"?>
<config xmlns:xsi="" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Store:etc/config.xsd">
    <preference for="Magento\Framework\Session\Config\ConfigInterface" type="namespace\module\Session\CustomConfig"/>

file : Session/CustomConfig.php

namespace namespace\module\Session;

use Magento\Framework\Session\Config as DefaultConfig;

class CustomConfig extends DefaultConfig
    public function setCookiePath($path, $default = null)
        parent::setCookiePath($path, $default);

        $path = $this->getCookiePath();

        //check and update path of cookie
        if (!preg_match('/SameSite/', $path)) {
            $path .= '; SameSite=None';
            $this->setOption('session.cookie_path', $path);

        return $this;

NOTE : replace namespace & module with your namespace and module.


It may help you!
