Which passwords can be called strong?

Passwords are on our data guard. And the degree of their reliability plays an important role. Obviously, it will not be easy to crack a complex password. But there are many personal accounts and systems that require authorization. And remembering dozens, if not hundreds of different combinations of symbols is almost impossible. What kind of password can you call a reliable one? To answer this question, you need to turn to those methods that are used by various unscrupulous people to crack someone else’s passwords in order to access their data.
The easiest and at the same time the most effective way to crack other people’s passwords is to brute-force them with the help of special crackers for all available dictionaries (if you use some words in your password that are present in Russian or English dictionary, or a combination of them, then your password is cracked pretty quickly), and the usual brute force – when all possible combinations of numbers and letters are searched, and first one-character combinations, then two-character, three-character and so on. Sometimes there are combinations of the first and second methods.

Examples of passwords that can be cracked very easily:



  1. Your birthday or phone number in digital form, for example: “20061989” is June 20, 1989. Such a password will be cracked very quickly.
  2. Names, surnames, pet names like “pushistik” is fluffy. This password will also be cracked very easily by dictionaries.
  3. Shorty passwords like “mama” or “sun” will also be opened by attackers almost instantly.

So, what are the basic rules for creating a strong password? There are several basic rules:

  1. Your password must be at least 10 characters long. Why
  2. ? The fact is that the longer the password is, the more time it takes to crack it with a brute-force attack. And with each new character that increases the length of the password, the complexity of breaking it increases in hundreds and thousands of times.
  3. Your password should not contain dictionary words, because in this case it will no longer matter how long it is, intruders will still be able to pick it up from existing dictionaries using their programs.
  4. It is desirable to use Latin letters when creating a password, and not only lowercase, but also capital letters. Please note that a password without uppercase letters and the same password, but with the use of uppercase letters are two different passwords. For example, if you have set a password in WinRar of the following type: “masKtroit”, the password “masktroit” will no longer be suitable for this archive. It is also very desirable to use at least one number in the password to make it even more complex.

 

There is an interesting service on the Internet, thanks to which you can approximately estimate reliability of your password and approximate time of its breaking:



Password security check

He will estimate the approximate number of days it will take to crack it, and also will show you how long different computers, from the weakest to the most powerful, can handle it.

As you can see in the figure below, it will take 36 years to crack a fictitious password on a regular computer.

Hardly anyone can remember a twenty character set like GdzIQaZyVaFgbh7dlu46. In fact, it is quite “painful” to use such passwords at all. On the other hand, they will be really hard to crack. Such passwords are good for systems that require special security and are not used frequently.</p><p>A passphrase can be used as a password by pre-encoding it. For example, in English “I want to be at the beach” encoding may look like <b>iw2b@theBeach</b>. A memorable password, which will be difficult enough to crack. It is possible to find a different ending for each system. Some systems even allow using the full sentence as passwords. Such passwords will not be forgotten and will be quite reliable.</p><hr/><p id=Practically anyone will agree: yes, a strong password is really important, but at the same time it’s so hard to remember! So many people don’t even try to clutter up the memory with complex passwords, often use the same password on multiple resources and so on. In general, it seems that in most cases users prefer to ignore security rules rather than look for an effective solution.

    Please use strong passwords! The idea that passwords are hard to remember is not only wrong, but also unsafe. Remember these golden rules:

    • Secure password is not necessarily a combination of random characters, it is a sequence of characters that is difficult to crack. And it’s not the same thing!
    • Create passwords based on phrases that mean something to you and you will remember them easily!
