Take physical security seriously

If you’re riding the train, waiting in line at a coffee shop, or standing in a crowded elevator, try not to type in passwords in plain sight or without them being scrambled. Someone behind you could be watching what you type as you log into Facebook or make a payment on Amazon. If you’re in public and you have to type in sensitive information, make sure your screen is blocked, or that you’re using a specialized privacy screen on a PC or Mac.
