For those who have something to hide
There are people who are simply 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 USB flash drive, it is always lying around somewhere. Therefore, of course, the lock for a flash drive with a secret code is not useful to me . But for citizens who have something to hide, perhaps it will be useful to purchase such a little thing. The most important thing here is not to forget the secret code.
