Four Password Mistakes That Make Accounts Easier to Compromise

Weak passwords remain a risk, but modern account defense is not simply adding punctuation to a short familiar word. Guessable patterns, password reuse, personal clues and predictable substitutions make passwords easier to attack. A safer approach combines long unique credentials, a trusted password manager, compromised-password screening and appropriate multi-factor authentication.

The Predictability of Familiar Words

Humans are creatures of habit, and this trait can prove detrimental when creating passwords. A password must be both secure and memorable, but often, in the interest of convenience, we choose words that hold personal significance or are easy to recall. This can include names of pets, family members, favorite sports teams, popular culture references, or common phrases. While these passwords are easy to remember, they also make it easier for hackers to guess.

These passwords, though seemingly personal or unique, fall into a predictable category. Cybercriminals know that people often use emotionally significant words or phrases that are familiar to them. These passwords are among the most commonly used across the internet, making them prime targets during hacking attempts. Large-scale password breach databases often show that the most frequently used passwords include names, popular culture references, or simple emotional expressions, such as “love,” “baseball,” or “12345.”

Why Familiar Words Are Easy to Guess

Attackers no longer have to guess passwords at random; they use sophisticated techniques that leverage massive databases of previously breached passwords. Hackers know that people tend to use familiar, easily accessible information in their passwords. By using tools like dictionary attacks, which systematically test common words and phrases, cybercriminals can quickly identify a password based on predictable patterns.

For instance, a user’s password might include the name of their favorite movie or sports team, such as “RedSox2020.” Attackers will be well aware of these kinds of combinations and will specifically target them when attempting to crack passwords. With password-cracking tools running at incredibly fast speeds, these types of passwords are among the first combinations to be tested. What seems like a creative and personal password can often be guessed in mere seconds by attackers using advanced algorithms and machine learning techniques.

Why Familiar Patterns Are Easy to Guess

Attackers don’t rely on guessing random combinations of characters. Instead, they use tools that take into account human behavior and common password structures. Keyboard sequences are easy for users to type, but they are also among the first patterns that attackers target. Hackers can use tools like HashCat to apply known pattern-based rules, testing combinations that include simple horizontal sequences (like “qwerty”), number patterns (like “123456”), or common keyboard diagonals (like “qazwsx”).

Security experts often recommend avoiding these patterns altogether. Even adding a number or special character to the end of a sequence, such as “qwerty123!” or “asdfgh#,” does little to make the password more secure. These small modifications are predictable and don’t provide much additional protection against attackers.

How to Avoid Keyboard Sequences

The best way to create a secure password is to avoid predictable patterns entirely. Instead of using sequences like “123456” or “qwerty,” consider using a combination of unrelated characters, numbers, and symbols to increase the complexity and randomness of your password.

These passwords contain a mix of upper and lowercase letters, numbers, and symbols, but they don’t follow any predictable patterns. Each character is placed randomly, making it much more difficult for attackers to guess. In addition to this, you can consider using a password manager to generate and store long, unique passwords for each service you use.

The Appeal of Keyboard Sequences

One common password creation habit that many users rely on is using keyboard sequences. These are strings of characters that follow an easily recognizable pattern on the keyboard, making them simple to remember and fast to type. Examples of these sequences include:

While these sequences may seem like they add complexity to your password, they provide a false sense of security. Many users turn to these patterns because they feel random or varied, but they are some of the first combinations that attackers will attempt when cracking passwords. Password-cracking tools are specifically designed to recognize and test these sequences quickly.

Why Keyboard Sequences Are Vulnerable

The reason keyboard sequences are vulnerable is that they follow a predictable pattern. When users create passwords using these sequences, they are relying on a combination of characters that attackers already know to be commonly used. Modern password-cracking tools, like HashCat and John the Ripper, are specifically designed to exploit these predictable patterns. These tools can perform brute-force attacks at lightning speeds, making it easy for hackers to crack passwords based on common keyboard sequences.

Password-cracking tools use what is known as “rule-based attacks.” These attacks are based on patterns that have been derived from analyzing real-world password leaks. Since keyboard sequences are so commonly used, they are at the top of the list of patterns these tools test. A password like “qwerty123” or “asdfgh!789” would likely be cracked in seconds.

How Attackers Exploit Keyboard Sequences

When hackers attempt to crack passwords, they rely on statistical analysis and data sets that include common keyboard sequences. These data sets are built from leaked password lists, which often contain millions of commonly used passwords. Since keyboard sequences are so popular, they are included in these lists.

Attackers use tools that can apply these common patterns and search for variations. For example, if an attacker knows that “qwerty” is a common password, they will start by testing combinations like:

How to Avoid Using Keyboard Sequences

To create a more secure password, it’s essential to avoid using keyboard sequences altogether. Instead, opt for passwords that are random, long, and diverse in terms of characters. Avoid using any obvious patterns or sequences, and focus on creating a combination of letters, numbers, and symbols that is truly unpredictable.

One of the best ways to create strong passwords is to use a password manager. Password managers can generate long, complex, and unique passwords for each of your accounts, ensuring that you don’t fall into the trap of using easily guessable patterns. With a password manager, you don’t have to worry about remembering complicated passwords, as the tool will handle all of that for you.

How Attackers Leverage Personal Information

Hackers often target personal information because it significantly reduces the number of possibilities they need to test. Password-cracking tools like HashCat and John the Ripper can easily incorporate known data into their attacks. For instance, these tools can combine commonly used words with dates, names, or locations to create a list of likely password combinations. Once attackers have access to even basic personal details, such as a person’s birthdate, pet name, or favorite team, they can significantly narrow down their password guesses.

This is particularly dangerous because many password-cracking tools are now designed to work much more efficiently. By exploiting social media data, personal details, and common patterns, these tools can crack passwords in seconds or minutes rather than hours or days. It’s a matter of narrowing down the possibilities by exploiting the predictable behavior of users when creating passwords.

Real-World Example: How Personal Information Can Be Used

Let’s consider a hypothetical scenario: an attacker knows that you are a fan of a particular sports team, and they can access your social media account, where you’ve posted about your team. With this knowledge, they can create passwords like “Lakers2024” or “BostonCeltics1995.” These passwords are based on common personal details and public knowledge, and while they may seem unique, they are easy to guess for an attacker who knows how to exploit this type of information.

Studies have shown that attackers often begin their password-cracking attempts by targeting these personal details, including the most common first names, last names, city names, and even pet names. Once they have a starting point, they can quickly expand their list by adding numbers or symbols at the end, using commonly known patterns like “123” or “!” to increase the chances of success.

How to Avoid Using Personal Information in Passwords

To avoid the risks associated with using personal information in passwords, the first step is to stop using any predictable details like birth years, names, or favorite numbers. Instead, focus on creating passwords that are completely random and unrelated to anything that could be easily guessed.

Instead of relying on personal details, use a password manager to generate long, random passwords that include a mix of uppercase and lowercase letters, numbers, and special characters.

The Role of Password Managers and MFA

Creating a truly random and secure password can be challenging, especially when you need to manage multiple passwords for various accounts. This is where password managers come in. Password managers can generate and store complex passwords for you, eliminating the need to remember each one. By using a password manager, you can ensure that each password is unique, random, and free from predictable patterns.

In addition to using password managers, enabling multi-factor authentication (MFA) adds an extra layer of security to your accounts. MFA requires something you know (your password) and something you have (such as a code sent to your phone or a biometric scan) to log in. Even if an attacker manages to crack your password, MFA can prevent unauthorized access.

Applying these lessons

Use a password manager to generate unique credentials, move sensitive accounts to phishing-resistant sign-in where available and plan account recovery. Do not reuse a password after any known exposure. Service operators should avoid arbitrary routine password changes unless compromise is suspected, and should support long passwords rather than obscure composition rules.
