Question 1

Is my password safe to type into this tool?

Accepted Answer

Yes — completely. All strength analysis runs in your browser using JavaScript. Your password is never sent to any server, stored in a database, or logged anywhere. You can verify this by checking the Network tab in DevTools while using the tool.

Question 2

How is password strength calculated?

Accepted Answer

We calculate Shannon entropy — the mathematical measure of unpredictability. It's based on the character pool size (lowercase, uppercase, numbers, symbols) multiplied by password length. Higher entropy = exponentially harder to crack.

Question 3

How accurate is the crack time estimate?

Accepted Answer

The estimate assumes 10 billion guesses per second — a realistic figure for modern GPU-based attacks. Real-world crack time depends on the attacker's hardware and whether they have the hash. It's a theoretical worst-case estimate, not a guarantee.

Question 4

What makes a password truly strong?

Accepted Answer

Length is the single most important factor — each additional character multiplies cracking time exponentially. 16+ characters with mixed types (upper, lower, numbers, symbols) is excellent. Avoid dictionary words, names, and dates. Use our generator for instant strong passwords.
