I am also stuck on the last part, I get a good "the answer is" string but the password doesn't look correct and certainly ISN't correct. I have tried around for hours now and it seems like the solution should be fairly obvious by now, but i can't it, if someone may be so kind to PM me pls,...
Imo this challenge is pretty dumb. I mean almost everyone knows immediatly what to do, yet the most logical solutions are not working and you have to resort to guess one right answer out of many. This could be changed to make more sense...
