How It Works
We use Entropy Analysis to determine how unpredictable your password is. The tool checks for:
- Common dictionary words and patterns.
- Keyboard patterns (e.g., "qwerty").
- Character variety (uppercase, numbers, symbols).
- Known leaked password lists.
Security FAQ
Is my password sent to a server?
NO. All calculations happen locally in your
browser using JavaScript. Your password never leaves your device.
What makes a password strong?
Length is key. A longer phrase (passphrase) like "Correct-Horse-Battery-Staple" is often
stronger than a complex short password. Use at least 12 characters.
