Passwords and locked terminals are a recurring obstacle in Directive 8020, and Carter's PC is the first one that trips players up in Episode 2. The game gives you a clue, but it's easy to miss if you're rushing through Crew Quarters trying to avoid whatever's lurking nearby. The good news: once you know where to look, this takes under a minute to solve.
What is the code for Carter's PC?
The code for Carter's PC is 2808. The game also accepts 0828 as a valid input, since the password is based on a date that works either way around (day-month or month-day). Both unlock the terminal and trigger the same cutscene.
If one format doesn't work on your first attempt, just flip the order. Enter 0828 if 2808 fails, or vice versa. Both are accepted by the game.

Post-it note clue on monitor
Where to find the clue for Carter's PC password
The game doesn't hand you the code directly. You have to piece it together from two things in the environment, both close to Carter's room.
Step 1: The post-it note on Carter's monitor
Look at the front of Carter's monitor. There's a post-it note that reads "Luna's" with an arrow pointing toward the screen. This is the first half of the puzzle: you're looking for something connected to someone named Luna.
Step 2: The calendar in Crew Quarters
Leave Carter's room and head into Crew Quarters. Turn right and you'll see a calendar mounted on the wall. Walk up to it and press the left mouse button to inspect it. The calendar shows the month of August. Look at the 28th, and you'll find "Luna's Birthday" written there in bold.
That's your code. August is month 8, and the 28th is the day: 2808 (day then month) or 0828 (month then day).
You can only interact with Carter's PC once. After you enter the code, a cutscene triggers immediately. There's no second chance to browse his files, so don't expect to revisit the terminal.
What happens after you enter the code?
Once you interact with the terminal using the correct code, a cutscene plays showing Simms walking into Crew Quarters. A new objective appears instructing you to follow her. Head through Crew Quarters and into the Lounge, where you'll find Simms standing in front of a monitor displaying a log of a conversation between her and Carter. Watching this advances the story and deepens Eisele's suspicions about what's been going on aboard the ship.
The PC itself serves one narrative purpose: triggering that Simms encounter. There are no additional files to read or items to collect from it.
This puzzle is part of the broader mystery surrounding Carter and Simms in Episode 2. Pay attention to the conversation log Simms is watching, as it feeds directly into later story beats.
Why does the game hide the code this way?
Directive 8020 uses environmental storytelling for most of its puzzles rather than spelling out solutions in a menu or journal. The post-it note and the calendar are both placed logically: Carter wrote a reminder to himself about a birthday, and the arrow on the note tells you where to look for the connection. It's a clean design that rewards players who actually read the environment instead of button-mashing through every interactable object.

Directive 8020 sits firmly in the adventure games tradition of using environmental clues to gate progress, and this particular puzzle is one of the more satisfying examples of that approach in the game.
