Twig in Symphony. How to use the same variable twice in a template?

Question

Twig

Passing an array to the template:

[
      'candidates' => $candidateRepository->findAll(),
 ]

The template accesses the same variable twice.

{{ candidate.accessToken }}
{{ candidate.accessToken }}

The value is displayed only once.

Can you tell me how to use the same variable twice in a Twig template?
