How secure is your password?

Your password could be cracked instantly.

Millions of accounts are targeted by cyberattacks every day. Yet the vast majority of us still use weak passwords: birth dates, simple words, or combinations of numbers alone. So how long does it take to crack these passwords?

Cybersecurity company Hive Systems answered this question with comprehensive data in 2023. They calculated the time it would take for a modern computer to crack passwords of varying complexity using brute-force methods. The results are both surprising and highly instructive.

What is a Brute-Force Attack?

A brute-force attack is a method of trying every possible combination of a password one by one. Since modern computers can test billions of combinations per second, short and simple passwords can be cracked almost instantly.

This study examined five different types of passwords:

1. Only numbers (123) — the weakest

2. Lowercase letters only (abc) — weak

3. Uppercase and lowercase letters (AaBb) — middle

4. Numbers + uppercase/lowercase letters (1aA2) — strong

5. Numbers + letters + symbols (1aA2!@#) — the strongest

Data: Breakpoint Time Table

The table below shows the cracking times for passwords between 4 and 18 characters at five different complexity levels. Red cells represent low security, and green cells represent high security. 5 Critical Findings from the Data

1. Almost any password up to 11 characters long is at risk.

Passwords of 11 characters or less can be cracked within hours or months, even if they contain symbols. An 11-character password consisting only of numbers, however, is cracked "instantly." This means that the password lengths many users still employ are in a critically vulnerable zone.

2. Adding symbols dramatically increases the duration.

The comparison for passwords of the same length is striking: a 12-character password containing only numbers can be cracked in 1 second, while a 12-character password containing numbers, letters, and symbols can last 15,000 years. Adding symbols can increase security tens of thousands of times.

3. 14+ characters is where real security begins.

Hive Systems' recommendation is clear: use at least 14+ characters for good security. A 14-character password containing numbers, letters, and symbols can take up to 77 million years to crack. In practice, this means it's virtually impossible to break.

4. The result remains the same for those using only numbers.

For passwords using only numbers and up to 18 characters, the longest validity period is 6 days. Therefore, no matter how long they are, passwords consisting only of numbers never provide sufficient security. PIN codes and passwords composed solely of numbers pose a significant risk.

5. Complexity can be more important than length.

While an 8-character password containing only lowercase letters lasts 6 hours, a 9-character password consisting only of lowercase letters is cracked in just 1 minute. This shows that complexity can be more critical than length — using both together provides the strongest defense.

What should you do? 5 Practical Suggestions

• Use at least 14 characters.

This is the clearest recommendation of the research. For characters of 14 or more, cracking them with the right combination becomes practically impossible.

• Be sure to include a symbol.

Symbols like !, @, #, $, and % increase the strength of your password by tens of thousands of times. This small touch makes a big difference.

• Mix uppercase and lowercase letters.

Using only lowercase letters significantly reduces security. Mixing letters multiplies the number of possible combinations.

• Distribute the numbers randomly.

Instead of using your date of birth or sequential numbers (1234), insert numbers in the middle or unexpected places in your password.

• Use a password manager

Remembering such complex passwords is impossible. Tools like LastPass, Bitwarden, or 1Password can generate and store strong and unique passwords.

Conclusion

While cybersecurity may seem like a complex subject, password security is based on a simple formula: length + complexity = security. The data unequivocally demonstrates this.

The idea that "who would hack my account anyway?" is no longer valid. Automated attack bots operate randomly, not targeting specific individuals, and find weak passwords in seconds. Even the smallest effort to strengthen your password dramatically increases your account security.

A single step you take today — updating your password to include 14+ characters and symbols — could protect you from millions of potential cyberattacks.
