Thought Password

Private residences on Typhon are locked with a uniquely generated thought password. Each password is derived from an algorithm which analyses thought patterns of residents to ensure that it is something that has never been thought before in the history of the tower, but is easily understood. It is therefore a statistical impossibility for anyone else to open the door, as nobody has ever thought that thought before. To open the door, residents must grasp the handle and visualise their unique thought password.

Datapads are also assigned thought passwords, however residents can generate their own passwords for these. They are instructed to think of something that makes them happy. For many, this would be a loved one, a cherished pet or a song, however Sven Gorsen did not have these things so was recommended to use one of the times his life was in peril and he survived.

Example
Resident Gorsen's thought password to his residence is:

"You are running through a forest and see a hive hanging low from the branch of a sycamore tree. If you do not know what a sycamore tree looks like, you can substitute oak or cedar or any other large tree. You think it may be fun to throw rocks at the hive, you are misguided. Bees begin pouring out, an unending torrent of bees. They are swarming you. They are stinging you. And you are flailing in a futile attempt to get them off. It's worse now, and they have crawled inside of you. In through your tear ducts and down your throat, muffling your screams. Now they are the ones who are desperate, desperate to escape their new fleshy prison. They bite and sting in an attempt to escape from you, but you have no way of letting them escape their bonds despite it being the only thing in the world that is important to you at this very moment."
