I recently installed a door to my ship, after installation I locked it. Now the rules say: "Once a door is locked, it requires either the password, or a keycard with the password appended, to move through the door."

I tried it out by moving through it.. and went through the next room >.>

I was expecting it to ask for the password or something and I don't have a keycard with me, does this mean that owners of the entity with locked doors can move freely?

The owner can do that, yes. Perhaps the commander as well, never had the opportunity to test that one myself.

Thanks.
