    $\begingroup$ Is the competition still ongoing? $\endgroup$ Oct 29, 2017 at 21:06
  • $\begingroup$ @BeastlyGerbil No, It has ended approximately two days ago, the time to solve all tasks was 6 hours, and this was in category of harder tasks. $\endgroup$

If we

take each block of 59 ./# as a single line

then we get

..######...#######..##......##.########...#######..##....## .##....##.##.....##.##..##..##.##.....##.##.....##..##..##. .##.......##.....##.##..##..##.##.....##.##.....##...####.. .##.......##.....##.##..##..##.########..##.....##....##... .##.......##.....##.##..##..##.##.....##.##.....##....##... .##....##.##.....##.##..##..##.##.....##.##.....##....##... ..######...#######...###..###..########...#######.....##...

so it would seem the password is

COWBOY.
