Took me a while to figure out the REAL password too. Here’s a hint:
Once you get the “first” password, it’ll be pretty long. Try to decode the arrays at top. Some of them are just trolls, but one of those trolls might tell you that a certain part of that password can be left out.
You’ve already done the hard part, this is the easy part. Good luck!
and of course, make sure you submit the key in the HTB{username:password} format.
