Why is csrf cookie not always created in yii2?

Question

Yii

The problem is that when I clear cookies, the csrf of the cookie is not saved, but if I switch to the standard layout, the cookie is saved and then I switch to my layout and everything works.
I've added the csrf meta.
Layout files are the same.
Php-7
OpenServer
Mongodb
What could be the problem? thank.

Answer 1

such a problem may arise due to the absence of $this->beginPage() in the layout or the output of csrf meta tags <?= Html::csrfMetaTags() ?>

Answer 2

Isn't the CSRF Token stored in the session?
According to the rules of CSRF, the Token is stored in the session, and every time the pages are updated, it changes the key.
