Why Use Our Password Generator?
Cryptographically Secure
Uses crypto.getRandomValues() — the same randomness standard used in encryption. Not Math.random().
100% Local Processing
Your passwords are generated in your browser and never sent anywhere. Zero server involvement.
Fully Customizable
Control length, character types, and generate multiple passwords at once. Your rules, your passwords.
Free & No Sign-Up
No account needed, no limits, no ads. Just open and generate. Works on any device.
Frequently Asked Questions
Is this password generator truly secure?
Yes. We use the Web Crypto API (crypto.getRandomValues()), which provides cryptographically secure random numbers. This is the same standard used for encryption and security certificates. Unlike Math.random(), it cannot be predicted.
Are my generated passwords stored anywhere?
No. All passwords are generated entirely in your browser using JavaScript. Nothing is sent to our servers or any external service. When you close or refresh the page, the generated passwords are gone.
How long should my password be?
We recommend at least 16 characters for strong security. For high-security accounts (banking, email), use 20+ characters with all character types enabled. Every additional character exponentially increases the number of possible combinations.
What makes a password strong?
A strong password combines length (12+ characters), randomness (not a dictionary word), and variety (uppercase, lowercase, numbers, and symbols). Our strength meter measures entropy — the mathematical measure of unpredictability — to give you an accurate assessment.
Can I generate multiple passwords at once?
Yes! Use the "Batch Generate" section to create up to 10 passwords at once. You can copy all of them with one click.
What is entropy and why does it matter?
Entropy measures the unpredictability of a password in bits. Higher entropy means more possible combinations an attacker would need to try. A password with 80+ bits of entropy is considered very strong. Our generator shows you the entropy in real time.
