Unknown Twig function csrf_token

[Guibzs]

See symfony-docs/security/csrf_in_login_form.rst

There's no more csrf_token function included in twig since Symfony 4.0.
Or is there a missing composer require ?

You are right. This becomes a bit tricky when using Symfony 4. The "easy" solution is to install the Form component for the function to be available. If you want to solve this in a cleaner way, you may want to implement the function yourself. You can take a look at symfony/symfony#25197 to see how easy this is in fact.

@Guibzs good catch. The good solution will come in Symfony 4.1 thanks to the change made by @xabbuh, but meanwhile we can improve this article as proposed in #8821.

Ran into same issue just now, so we can at least mark this confirmed ;)
