 > [Study Kerckhoffs's principle](https://en.m.wikipedia.org/wiki/Kerckhoffs%27s_principle) - The principle which holds that a cryptosystem should be secure, even if everything about the system, except the key, is public knowledge. This concept is widely embraced by cryptographers, in contrast to security through obscurity, which is not.
 
 Let’s say we deal with a [Duress](https://play.google.com/store/apps/details?id=me.lucky.duress) tool. As such, it can be used wrong (e.g. weak password), or used to do bad things (e.g., exfiltrate intellectual property). On the opposite, we can just use [Steganography](https://officercia.mirror.xyz/8ecJG-s_5E6J1t-h8gUNGqV3hbX8If-E5NnrFrOJHUA) and a small paper, without even touching the computer.

 > For a perfect-level privacy, always generate complex passwords and write them down on a notebook. It takes time but saves headache. Somewhere along the line, the 'stop writing passwords on sticky notes' narrative got misinterpreted as 'never write them down'. There's nuance to it!
 
 Using a string of unrelated words while still meeting the dictionary requirement makes it easy to have an extremely secure password while still being able to remember it. If fully relying on a password manager, a password of 20+ characters in length that is randomly generated can be used.
