How to create a strong password? It is not difficult!

Access to a computer, several e-mail boxes, a cloud disk full of private photos, a profile on a social network ... our data is practically everywhere. How to protect them against unauthorized access? The first barrier we can put up is the password. The right password. Only there is a problem with it - a strong password is usually associated with an incomprehensible, completely random string of characters that is impossible to remember. If we create them in the right way, then the only people who will cause problems will be the ones we want to protect our data against. For us it will be completely clear and simple.

So how do you prepare them? How to create strong passwords? You will learn this from our guide.

Password Length

Here the rule is simple - the password should contain not less than 8 characters. The more of them (though you should not exceed 127 characters), the better, of course. Each subsequent sign is an increase in the number of combinations necessary to break it, and thus increase the level of security.

Characters in a password

In most cases (the exception is the payment card PIN), we can use the four most important categories of characters to set a password. Those are:

Characters from each of these categories should be included in the password. Why? Again - this greatly increases the complexity of the password, and thus - its strength and security. To illustrate this, we will present a few numbers (if you take our word for it and you are only interested in practical issues, you can go straight to the next step).


If we create a password consisting only of numbers, then we will have only 10 characters (from 0 to 9). So the number of combinations necessary to break it is relatively small, especially in the case of passwords with a limited length, as the already mentioned PINs for payment cards. In their case, the maximum number of combinations is 10,000 attempts. Will this password be strong? Absolutely not.


Passwords consisting of letters, but without distinguishing their size, are now more secure, but you can still not call them strong. To create it we can use 26 different characters (we take into account the characters available on standard keyboards), in this case 2 * 1011 possible combinations.


Passwords, which still consist of only letters, but with differentiation of sizes, are already 52 characters available. The number of possible combinations - 5 * 1013. Will this already be a strong password? Not yet. It will no longer be weak, but its strength will be average at best.


Passwords consisting of lowercase and uppercase letters and numbers will be somewhat safer, enabling the use of as much as sixty-two characters and increasing the number of possible combinations to 2 * 1014. Theoretically, most of these passwords will be considered strong passwords, but we will soon prove that they do not always have to be.


Passwords made of uppercase and lowercase letters, numbers and special characters will be much stronger (33 symbols available on most standard keyboards). 95 different characters that we have at our disposal are as many as 7 * 1015 possible combinations, so we can achieve a really high level of security.


So it is not difficult to guess which of the above possibilities you should use. Yes, if we want to create a strong password, it should consist of characters in all available categories.

Instead of inventing the password yourself, we can use a program that will generate a secure password for us. It will prepare for us completely (as far as possible) a random string of characters that will be no less strong, but also no less complicated than the password prepared according to the method described in the first point.
