Why is cron not getting data without access_token vk?

Question

PHP

Good morning.
I have a basic check if the user is logged in through VK

if (empty($token)) { 
echo 'Не залогинен';
} else {
echo 'Залогинен';
}

So, when I take and write the code

(получения, к примеру числа друзей пользователя с вк апи и заношу их в  бд)

and I write it exactly in that part of the code when the user is logged in, but the cron does not update the number of the user's friends.
In general, when I write code in the part of the code where the user is not logged in and I send not the number of friends, but any prime number. then it is updated. I was told to somehow pass the access_token so that the cron understands that the user is logged in, but how??
Many thanks to everyone who responds! :)
