I am not sure, if I understand your question correctly.  But passing the
token to another code block is easy.

There are two straight forwards ways:

1. As a variable

--8<---------------cut here---------------start------------->8---
#+name: authenticate
#+begin_src sh
  ## do sth to generate a token
  token="uagpb"
  echo "$token"
#+end_src

#+name: usethetoken
#+header: :var token=authenticate()
#+begin_src sh
  echo "${token}.ext"
#+end_src

#+results: usethetoken
: uagpb.ext
--8<---------------cut here---------------end--------------->8---

2. Using noweb

--8<---------------cut here---------------start------------->8---
#+name: authenticate
#+begin_src sh
  ## do sth to generate a token
  token="uagpb"
  echo "$token"
#+end_src

#+name: usethetokenvianoweb
#+begin_src sh :noweb yes
  token=<<authenticate()>>
  echo "${token}.ext"
#+end_src

#+results: usethetokenvianoweb
: uagpb.ext
--8<---------------cut here---------------end--------------->8---

HTH,
Andreas
