Common Password Mistakes to Avoid

Predictability is the Enemy of Security

When cybercriminals attempt to breach an account, they don't start by guessing random strings of characters. They start by guessing the things human beings are most likely to type. Humans prioritize convenience and memory, which leads to highly predictable patterns.

To secure your digital identity, you must actively avoid the following common password mistakes.

1. Keyboard Walking and Spatial Patterns

One of the most frequent mistakes is using the physical layout of the keyboard to generate a password. Patterns like qwerty, asdfgh, 123456, or qazwsx are incredibly common. Attackers are fully aware of this behavior, and spatial keyboard walks are among the very first patterns that automated cracking software attempts. Never use adjacent keys to form a password.

2. Formulaic Complexity

Many websites force users to include an uppercase letter, a number, and a special character. To comply while remaining memorable, users fall back on a standard formula: Capitalize the first letter of a word, append a number to the end, and finish with an exclamation mark (e.g., Autumn2024! or DallasCowboys1!).

This formulaic complexity provides a false sense of security. Modern cracking algorithms automatically apply these exact transformations to entire dictionaries of words, cracking them almost instantly.

3. Including Personal Information

Never use information that can be easily associated with you. This includes:

• Names of pets, children, or spouses.
• Birthdays or anniversary years.
• Hometowns, current street addresses, or high schools.
• Favorite sports teams or bands.

Attackers frequently scrape social media profiles (like Facebook, Instagram, or LinkedIn) to gather this exact information and feed it into custom dictionaries to launch highly targeted spear-phishing and cracking attacks against specific individuals.

4. Small Modifications for Different Sites

In an attempt to avoid reusing the exact same password, many users adopt a predictable shifting pattern. For example, using PasswordFaceb00k! for social media and PasswordG00gle! for email. If one of these sites suffers a data breach, attackers easily deduce the pattern and apply it to other major services. This is no better than reusing the exact same password.

5. Relying on Simple Substitutions (Leetspeak)

Substituting letters for visually similar numbers or symbols (e.g., changing "a" to "@", "e" to "3", or "s" to "$") was considered clever two decades ago. Today, algorithms explicitly check for these substitutions by default. P@$$w0rd is virtually identical in strength to password to modern cracking software.

The Solution

The only reliable way to avoid all these human errors is to remove the human from the generation process. Use a Password Manager to generate long, completely random passwords that contain no patterns, no dictionary words, and no personal information.
