In Chapter 7 of The Quarry, the story treads back to the point where Laura was held at the police station. As Laura, you can explore the area where you will eventually find Sherriff Travis Hackett's computer. To unlock the Bizarre Yet Bonafide trophy, you will have to figure out the device's password by following some hints.
How to unlock the Bizarre Yet Bonafide Achievement/Trophy in The Quarry
The computer can be unlocked by entering the Sherriff's birthday as the password. To figure out the password, start by leaving the cell and following the stairs to the rooms upstairs. Head inside the first room and you'll see a birthday card on the bulletin board to your right. After inspecting the card, Laura will figure out Travis's year of birth.
Exit the room and go to the last room on the floor for the next clue. In the left corner of the room, you'll find a calendar on which Travis would have marked his birthday. This was the final step in uncovering the password.
Finally, head downstairs to the office with the computer. Once you interact with the computer, Laura will automatically enter the password and unlock the device. Let your character explore the files and you will get the 'Bizarre Yet Bonafide' trophy pop-up and it will be added to your achievements list.
Although the objective itself is fun, you can skip it if you are in a hurry to complete the 10-hour long game. You can also listen to the Bizarre Yet Bonafide - The Podcast of the Paranormal Episode 1 below.
