Frequently Asked Questions

Is my password sent to a server?

No. All analysis is done entirely in your browser. Your password never leaves your device.

What score makes a password strong?

A password scoring "Strong" typically has 12+ characters with mixed character types and no common patterns.

How is the password strength calculated?

We use a sophisticated algorithm which estimates the password strength by analyzing patterns, dictionary words, common names, and predictable substitutions.

What does "estimated crack time" mean?

It is an approximation of how long it would take a hacker using modern hardware and guessing techniques to crack your password.

Why does my password show as weak even with symbols?

If your password contains common words (like "password123!") or predictable patterns, it is still vulnerable to dictionary attacks, regardless of the symbols used.

Should I use a passphrase instead of a complex password?

Yes, passphrases (e.g., "correct-horse-battery-staple") are often much longer and easier to remember, making them highly secure against brute-force attacks while being user-friendly.

Does length matter more than complexity?

In many cases, yes. A longer password (16+ characters) using just letters and numbers is mathematically harder to crack than a short 8-character password with many symbols.

Are password strength meters completely accurate?

No meter is 100% accurate, but ours provides a very reliable estimate based on real-world cracking techniques and comprehensive wordlists.

What should I do if my password is compromised?

Change it immediately on all sites where you have used it, and ensure you use a unique, strong password for each account moving forward.

Is this tool safe to use on public Wi-Fi?

Yes. Because our tool runs 100% locally in your browser, no data is transmitted over the network, making it safe to use even on unsecured connections.
