In the vast world of Fallout 76, the "Out of the Blue" quest, introduced as part of the Steel Reign update, presents players with a unique challenge. This quest requires solving a password puzzle to gain access to a lab area. The puzzle involves converting the phrase "Open Sesame Seed" into numerical codes using a simple letter-to-number substitution method. Here's a step-by-step guide on how to solve this puzzle and unlock the lab door.
Quest Background
The "Out of the Blue" quest begins at Fort Atlas, where Paladin Rahmani tasks you with locating the Blue Ridge Caravan Company. As you progress through the quest, you'll find yourself in a lab area with three password panels. The objective is to unlock the lab door by entering the correct codes into these panels.
Finding the Password Clues
To solve the puzzle, you need to find two crucial notes:
Reminder About Password: This note is pinned to the wall next to the password panels. It hints that the password involves converting words into numbers.
Open Sesame Seed Note: Located on a desk across from the password panels, this note contains the phrase "Open Sesame Seed," which you need to convert into numerical codes.
Converting Words to Numbers
To convert the words into numbers, use the standard alphabet-to-number substitution method, where A = 1, B = 2, C = 3, and so on. You can find a visual aid for this conversion on a blackboard in the lab area.
While navigating the post-apocalyptic world of Fallout 76, resource management, particularly managing your stash of caps, is crucial as you tackle quests like "Out of the Blue." Fallout 76 Caps, the primary currency in Appalachia, are essential for purchasing gear, ammo, and other vital items that can aid you in overcoming the challenges presented by quests. By efficiently earning and saving caps, you can better equip yourself for missions like solving the intricate password puzzle in the lab area, ultimately enhancing your overall Fallout 76 experience.
Password Codes
Using the alphabet-to-number substitution, the codes for each word are as follows:
Open: 12-11-22-13
Sesame: 8-22-8-26-14-22
Seed: 8-22-22-23
Entering the Codes
Start with the leftmost password panel and enter the code for "Open": 12-11-22-13.
Move to the middle panel and enter the code for "Sesame": 8-22-8-26-14-22.
Finally, enter the code for "Seed" in the rightmost panel: 8-22-22-23.
After entering all three codes, press the red button to the right of the panels to unlock the lab door.

Solving the "Out of the Blue" password puzzle in Fallout 76 requires attention to detail and a basic understanding of letter-to-number substitution. By following these steps, you'll be able to unlock the lab door and continue with the quest. The Steel Reign update has brought new challenges and opportunities to the game, making it an exciting time for players to explore Appalachia.
