Frequently Asked Questions

Common questions about SameSite Cookies

Yeah, probably. This plugin uses what's called "pluggable functions" supported in WordPress to replace wp_set_auth_cookie function. This means that any other plugin that tampers with the login cookie parameters will override this plugin, and this plugin may not even get a chance to do what it does.

Go to the Login page of your WordPress site, and open your browser's development tools. Inspect the HTTP POST request made by the browser when you submit the login form. The response headers for Setcookie response headers must contain Samesite=Lax (or the configured value) if the plugin is working. Note that cookies apart from the authentication cookies are not handled by this plugin, nor it makes sense to add SameSite attribute to them. See the screenshot as well.

No. PHP 7.3 officially added SameSite cookie support, but this plugin comes with a polyfill to extend support to all previous PHP versions.

Without SameSite cookie, WordPress core and third party plugins must implement their own CSRF checks, which can be overlooked, intentionally ignored, or sometimes not even have thought about, which can be the case for contributed plugin. This plugin attempts to solve this with different take and complement existing solutions.
