This can be unlocked at the Police Station after gaining the keys from Eddy. Instead of going to the break room, open the door to the reception, and here you can interact with the computer. If you want to skip the solution, choose:
User: D. Wilson
If you want to know how to figure this puzzle out, you'll want to see the memo about the password change next to the reception computer. Now, find D. Wilson's desk, where she left the memo on her desk. Go to the locker room (near the break room) and find her locker. Head back to her desk, look inside the drawer and take the key. Go to her locker and open it to find the post it note that says her password is the "20th birthday winner". Go back to her desk and inspect her birthday card to notice it's her 29th birthday. The game takes place in 2015. Her 20th birthday was in 2006. Look at the Iditarod poster, find 2006, and find the winner named "Salem".
