Warning This Section Does Contain Spoilers
Last episode we found and unlocked the Survivors website. Under News and Media on the Survivors website there is a section for "Starting To Gain Some Traction" and this has a password protected file and the hint is "To unlock, use the True Name of Thomas, who lit the world".
In the Veridical Codex Lux Page 16, "Thomas, called by the name of the heath, he who captured image and song, and lit the world."
Password is "heath"
