Frequently Asked Questions

How is password strength calculated?▾
The tool evaluates length, character variety (lowercase, uppercase, numbers, symbols), character mixing, and checks for common patterns. Scores range from 0-100 mapped to five strength levels.
How is the estimated crack time calculated?▾
It assumes a modern GPU cluster attempting 10 billion guesses per second with a brute-force attack. The time represents the average case (half the total possible combinations).
Is my password sent to a server?▾
No. The password never leaves your browser. All analysis is performed with client-side JavaScript. No network requests are made.
What makes a strong password?▾
A strong password is at least 12 characters long, uses a mix of uppercase, lowercase, numbers, and symbols, and avoids common patterns like "password123" or repeated characters.
Can I use this tool on my phone?▾
Yes, the password strength checker works in any modern mobile browser. Type or paste a password and instantly see the strength rating and estimated crack time.
Does this detect common password patterns?▾
Yes. The tool checks for common weak patterns like sequential numbers (123), keyboard walks (qwerty), dictionary words (password), and repeated characters (aaa). These patterns significantly reduce password strength.
How accurate is the crack time estimate?▾
The estimate assumes a worst-case scenario with a modern GPU cluster performing 10 billion guesses per second. Real-world crack times vary based on the attack method, hashing algorithm used, and available computing power.
