If a friend sets a password on the drone, and someone else presses E to enter the password, they can unlock it like normal. However, if the person doesn't enter a password and cancels out, the Drone then shows it is in use to the owner.
We have tested this with multiple people, and the only way the owner was able to get into their drone was if the original person who cancelled the password successfully enters it. Until then, no one can access the drone.
This means on a server, if you set a password on your drone and a stranger presses e on it, they can essentially lock up your drone.
Minor issue. Color of drone also only displays when close to the drone, when backing away it changes to default color.
