Question 1

How is my password strength calculated?

Accepted Answer

We use the industry-standard `zxcvbn` library, originally developed by Dropbox. It recognizes patterns, common names, dates, keyboard layouts, and popular dictionary words to provide a realistic estimation of how hard a password is to crack.

Question 2

Are you saving or logging the passwords I test?

Accepted Answer

Absolutely not. The password analysis runs entirely locally on your device via JavaScript. Nothing is ever sent over the network.

Question 3

What does the 'Crack Time' mean?

Accepted Answer

The crack time is an estimate of how long it would take a hacker using dedicated, high-speed offline hardware to guess your password using brute-force and dictionary attacks.

Question 4

Why did my password score low even though it has numbers and symbols?

Accepted Answer

If your password contains common words (like 'password', 'admin', or your name), keyboard patterns (like 'qwerty'), or dates, attackers will try those first. Modern cracking tools easily bypass simple character replacements like 'P@ssw0rd'.

Question 5

What is a 'Dictionary Attack'?

Accepted Answer

A dictionary attack is a method where an attacker tries millions of common words, names, and leaked passwords to guess your password. Our tool checks if your password is vulnerable to this.

Question 6

How can I improve my password score?

Accepted Answer

The easiest way to improve your score is to increase the length of the password and avoid common words. Using a 'passphrase' consisting of 3 or 4 random, unrelated words is highly effective.

Question 7

What are the 'Suggested Variants'?

Accepted Answer

We provide automatically generated, stronger alternatives based on your input. This includes breaking predictable patterns, substituting characters safely, or generating a memorable passphrase.

Question 8

Is a 100% score guaranteed to be unhackable?

Accepted Answer

No password is truly unhackable, but a 100% score indicates that it would take centuries for current hardware to crack it, making it exceptionally secure.

Question 9

Do password managers use this kind of scoring?

Accepted Answer

Yes, many reputable password managers use similar algorithms (like zxcvbn) to measure password entropy and warn users about weak passwords.

Question 10

Why does length matter more than complexity?

Accepted Answer

Every additional character exponentially increases the number of possible combinations. A long password of simple letters is often much harder for a computer to guess than a short password packed with symbols.
