Access codes for United cockpit doors accidentally posted online
My first thought was "aren't these rotated often? even just generated for every flight?", but then I rapidly thought about who would need to set them, and I decided it strange that the flight attendant would know the password at all... if the goal is to protect against an attacker, giving the password to anyone outside of the cockpit just makes them a target and a weakness; but once you go that far, I wonder why they need access codes at all?... the pilots should just lock themselves into the cockpit and they need neither a key nor an access code at that point, right? Isn't this needless complexity to have these codes?
