The Security Station Safe in the Life Support area of Talos I has a randomly generated code, meaning it is different for everyone in every Prey playthrough. However, where to find the code is the same every time.
The Security Station Safe code is found in the hallway that leads to the main lift. You have to find and search the body of Erica Teague.
