Level 3

With a little help from my friends

Solution

If we open the dev tools (f12) as earlier we will not see anything interesting. There are: header, paragraph, some text and a submit form. This form send basic HTTP request with token argument to the server.

Let's try to paste the same token as we have

CkMV20no7/ac8nwQnmU9j3W2dD07/csl5RNp8rBj3ibhOOTgGHMopGS4Ff2FFjnYUSvaZqnCf2A3TBBhm95T3tMzlGm+i1e3NE35D32xt2s=

Now we see the error message on the top of the page.

    I assume you used your own token or your friend is not remote enough.
  
Okay. Let's request this page again with any anonymous browsing utility

Now we have another token:

    CkMV20no7/ac8nwQnmU9j3W2dD07/csl5RNp8rBj3ibhOOTgGHMopGS4Ff2FFjnYUSvaZqnCf2A3TBBhm95T3tMzlGm+i1e3NE35D32xt2s=
  
Let's try.

Nice, now we have a new message on the top of the page

  Thank you for your friend's token. Continue with the next level.

The next level takes us to the Level 4 (task / solution)
