This extension is adjusting Cookie SameSite attribute issue since Chrome 80.

NOTICE: this extension is experimental.


Add SameSite attribute into Magento session cookie. For 3DS payment, payment gateways tend to send request via POST to Magento based website. However without SameSite=None for session cookie, Magento cannot continue any PHP session state. This extension set SameSite=None and make customers place order via 3DS payment or other ID integrations.

How to install

  • composer require veriteworks/cookiefix
  • bin/magento module:enable Veriteworks_CookieFix
  • bin/magento setup:upgrade


After 3.0.0-beta1, you can change SameSite cookie configuration from admin panel. Go to "Stores > configuration > web" and open cookie section. You can see "SameSite" field. By default, this extension sets SameSite configuration value to limited cookies. If you hope to update the list, please update web/cookie/affected_keys configuration value.


If you have any issues about this extension, open an issue on Github. Technical support question is same.
