For those who have something to hide

There are people just obsessed with security. For example, I got three alarms from the previous owner of my car! I use only one. I do not have a password on the computer, and anyone can take my flash drive, it is always somewhere lying around. Because I certainly do not need a lock for a flash drive with a secret code . But for citizens who have something to hide, it will probably be useful to purchase such a thing. The most important thing here is not to forget the secret code.
