I'm stuck on web_breaking_bad.
Basically, I need to somehow get access to the account financial-controller@frontier-board[.]htb, but nothing is working. I also can't forge JWT signatures... I even wrote a script for OTP to transfer money, but still no success.

I am stuck on this too. There is a py script that they provided that you need to complete and it gets the flag instantly but there are many things you need to complete

I already tested the above to see if it would work, and as a result, I got the following request:
but i got
HTTP/1.1 401 Unauthorized
Server: nginx
