If anyone ever has issues with me trying to control hints, this is why. Even on the server hints are restricted to a pre-approved list both so I know how to troubleshoot the difficulty but also make it so it's not just giving the answer away.
There are two hints I can give you:
1. Don't overthink it.
2. Much like Day 10, the scene before password input is a clue of where you should be looking or thinking about when trying to solve this.
