Frequently Asked Questions

Is my password safe while I test it?

Absolutely — all analysis runs entirely in your browser using client-side JavaScript. Your password is never sent over the network, stored, or logged anywhere.

What makes a password strong?

Length is the most important factor (12+ characters), followed by character variety (uppercase, lowercase, numbers, symbols) and avoiding common patterns (passwords, dictionary words, keyboard walks like 'qwerty').
