Sometimes you get really frightened when you find out how simple passwords people use. First, they are very simple, but there is also many people who would give away their password by just being asked. In this article, I will talk briefly about good password. Getting people to not give away their passwords is an entirely different problem. It doesn’t matter how good the password is if the owner doesn’t keep it a secret. But in this article, I will talk about how to create good passwords that are hard to guess and that can take a long time to generate through a brute force attack.
The goal is to have as impersonal password as possible so that nobody should be able to guess the complete, or parts, of the password. You shouldn’t use your name, phone number, address, pet names, name of acquaintances, your cars registration number and so on. Other people can easily get hold of that information. You also shouldn’t use any of the most commonly used passwords. Here is a link to a list of the most common passwords. It’s best if you use such a large character set as possible when making a password. This makes the password harder to guess and it takes longer to generate with a brute force attack. Ideally, you should use numbers, uppercase and lowercase letters and special characters. Below is a table showing how many variations of passwords that can be created from a number of characters for different character sets.
|Number of characters per character set|
|Number of characters used||10||36||62||100|
