Modern approach to generating secure passwords

For years, we have been fed instructions that today prove to be not only outdated but even harmful to our security. We all know the scenario: you try to create an account, enter your favorite word, and the system rejects it, demanding a capital letter, a number, and a special character. Frustrated, you change it to something like MyPassword1!, which the system deems strong. The reality, however, is different – for modern hacking algorithms, such a password is almost as easy to crack as the initial word itself. We must understand that the key to protecting our savings and privacy is not how many "weird" characters we type, but how long and unpredictable our secret string is.

Why have traditional password requirements stopped working?

The main reason old methods failed is the predictability of human behavior. When a system forces us to use specific elements, our brains seek the path of least resistance.

Statistics from thousands of data breaches show that if we must add a digit, we most often choose "1" at the end. If we must add a capital letter, it lands at the very beginning of the word. If a special character is required, in 90 percent of cases, it is an exclamation mark or an "at" symbol (@). Hackers do not need to guess each character individually – their programs are designed to check these typically human patterns first.

In effect, a password that seems complex to us is just another entry on a list of common patterns for a computer. This phenomenon means that perceived complexity only gives us a false sense of security, while actual protection is illusory.

The power of length vs. the illusion of complexity

Modern cryptography is based on a simple fact: every additional character in a password drastically, exponentially increases the time needed to crack it. The mathematics here take no prisoners. It turns out that a password consisting of sixteen ordinary lowercase letters is billions of times harder to crack than a short, eight-character password with capital letters and symbols.

This is because even for a supercomputer, overcoming the length barrier is much more costly in terms of computing power than guessing a predictable set of special characters. That is why cybersecurity experts today place immense emphasis on passwords simply being long. Every bit of uncertainty we add by extending the string becomes an impenetrable wall for today's attackers.

This issue is directly related to the concept of password entropy, the mathematical measure of its unpredictability, which you will read about in future posts on our blog.

Revolutionary guidelines from leading institutions

The change in approach mentioned here is not just the opinion of a few specialists, but the official position of leading organizations involved in national and digital security.

The American National Institute of Standards and Technology (NIST), in its latest publications, officially discourages forcing users to use a mix of different character types. Instead, they recommend that systems allow the creation of passwords at least 15, and preferably 20 or more characters long.

A similar position is held by the Polish CERT, which calls for moving away from archaic methods in favor of modern digital hygiene. According to these guidelines, it is best to create passwords that are unique for every service and not to force changes every 90 days unless a leak is suspected. Forced password rotation led users to create increasingly weaker and easier-to-guess combinations just to remember them.

Meet the word-based password method, or Passphrase

Since we know that length is key, a challenge arises: how do we remember a string of twenty random characters? The answer is the word-based password method, known as a passphrase. It involves combining several completely random words that have no logical connection to each other.

Imagine a combination like silver-clock-runs-forest. For the human brain, this is a sequence of images that is very easy to memorize by creating a small story in your head. For a hacking algorithm, however, it is a massive search space consisting of trillions of possible combinations. It is important, however, that these words are chosen randomly by a machine rather than by our imagination, which often suggests popular movie quotes or song lyrics. If you use words that are rare or specific, your security increases even further.

A very effective extension of this method is the use of elements such as local slang, which is completely absent from the global password databases used by criminals.

Why is it worth trusting modern generators?

Creating a strong password in your head is difficult because we humans are inherently schematic. Therefore, the safest option is to use tools that generate randomness for us.

Modern passphrase generators work in a way that guarantees the resulting password never leaves your device. Everything happens locally in your browser, which eliminates the risk of someone eavesdropping on the process of creating your new key. This approach ensures you can enjoy the highest level of protection without having to be an expert in mathematics or computer science.

Remember that in the age of artificial intelligence, which can analyze our habits faster than ever, a long and random passphrase remains one of the last effective barriers protecting our digital lives from unauthorized access.

Summary of modern password rules

Creating secure passwords requires us to abandon old habits. Instead of struggling to remember short, strange strings like P@ss1ord!, opt for long phrases composed of several random words.

Remember the three golden rules: the password must be at least 15 characters long, it must be unique for each account, and it should not be based on your personal data or popular phrases. Using a generator based on secure algorithms is the simplest step you can take today to realistically raise your security level.

As noted by one of the most prominent experts in the field of cryptography: "Password length significantly increases the time and computational resources required to crack it. A longer password exponentially raises the difficulty of a brute force attack, making it a crucial aspect of password strength" (Schneier, 2024). By following these tips, you build a foundation for your online security that will withstand cracking attempts by even the most advanced technologies.
