Why Strong Passwords Matter More Than Ever in 2026

Published by Aragorn · ZorbTool Blog

In 2024 alone, over 1.5 billion passwords were leaked in data breaches worldwide. Despite years of warnings from security experts, millions of people still use passwords like "123456", "password", and their own name followed by their birth year. Understanding why strong passwords matter — and how to create them — is one of the most important things you can do to protect yourself online.

How Hackers Actually Steal Passwords

There is a common misconception that hackers sit at computers manually guessing passwords. In reality, password cracking is almost entirely automated. Hackers use specialised software that can test millions or even billions of password combinations per second. There are three main attack methods you should understand.

A brute force attack tries every possible combination of characters systematically. A six-character password using only lowercase letters has around 300 million possible combinations — a modern computer can crack this in seconds. A twelve-character password using uppercase, lowercase, numbers and symbols has quintillions of combinations and would take millions of years to crack by brute force.

A dictionary attack uses lists of common words, names, and previously leaked passwords to guess credentials. If your password is a real word, a common phrase, or a password that has appeared in any previous data breach, it is extremely vulnerable to this type of attack.

Credential stuffing takes username and password combinations from one data breach and automatically tries them on hundreds of other websites. If you reuse the same password across multiple sites, a breach on one site compromises all of them.

What Makes a Password Truly Strong

Length is the single most important factor in password strength. Each additional character exponentially increases the number of possible combinations. A password of at least 16 characters is recommended for important accounts. Character diversity matters too — using uppercase letters, lowercase letters, numbers and symbols dramatically increases the password space. Randomness is equally critical — a truly random password like "xK9#mP2$vL7@nQ4!" is far stronger than a memorable pattern like "Password123!" even though they are similar in length and character types.

Why You Should Never Use Math.random() for Passwords

If you have ever written a password generator in JavaScript, you may have used Math.random() to generate random characters. This is a serious security mistake. Math.random() is a pseudorandom number generator — it produces numbers that appear random but follow a deterministic algorithm. A sophisticated attacker who knows when and where Math.random() was called can potentially predict its output. For cryptographic purposes, you should always use the Web Cryptography API's crypto.getRandomValues() function, which uses the operating system's cryptographically secure random number generator. This is exactly what ZorbTool's Password Generator uses.

Password Managers — The Practical Solution

The biggest practical challenge with strong passwords is that they are impossible to remember. The solution is a password manager — software that generates, stores and autofills strong unique passwords for every site you use. You only need to remember one strong master password. Popular options include Bitwarden (free and open source), 1Password, and Dashlane.

Two-Factor Authentication

Even the strongest password can be compromised through phishing attacks where you are tricked into entering your credentials on a fake website. Two-factor authentication (2FA) adds a second layer of protection by requiring a time-sensitive code in addition to your password. Enable 2FA on every account that supports it, especially email, banking, and social media.

The few minutes it takes to generate and store a strong unique password for each of your accounts could save you from the enormous disruption and potential financial loss of having your accounts compromised.
