How to disable cookies in Laravel 5?

Simply comment out the lines in app\Http\Kernel.php which related to cookies and sessions. The following ones which I found;

\App\Http\Middleware\EncryptCookies::class,\Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,\Illuminate\Session\Middleware\StartSession::class,\Illuminate\View\Middleware\ShareErrorsFromSession::class,\App\Http\Middleware\VerifyCsrfToken::class,

Hope it helps.

As of 5.7.0 the XSRF-TOKEN cookie is now optional. In order to disable it you just need to set the following in your /app/Http/Middleware/VerifyCsrfToken.php file.

protected $addHttpCookie = false;

I've just tested this in Laravel 6.0.
To have CSRF middleware running, and Laravel adding no cookies you need to disable (comment out) the following middleware:

\Illuminate\Session\Middleware\StartSession::class,\Illuminate\View\Middleware\ShareErrorsFromSession::class,

This will prevent Laravel from adding the laravel_session cookie.

To disable adding XSRF-TOKEN cookie, open up \App\Http\Middleware\VerifyCsrfToken::class middleware and set $addHttpCookie property to false
