Frequently Asked Questions
How secure are the generated passwords?
All passwords are generated using crypto.getRandomValues() which provides cryptographically secure randomness. The passwords are created entirely in your browser and never transmitted over the network.
How to generate a strong password online?
Simply adjust the length (we recommend 16+ characters), enable multiple character types (uppercase, lowercase, numbers, symbols), and click generate. The tool will create cryptographically secure passwords instantly.
Is this password generator tool free?
Yes, our password generator is completely free to use. No registration, no limits, and no hidden costs. Perfect for personal use, business, or development projects.
Can I analyze my existing password?
Yes! Switch to the Analyzer tab to check your existing password strength. Get detailed metrics including strength score, entropy, and estimated time to crack. All analysis is done locally for your privacy.
What is password entropy?
Entropy measures password randomness and unpredictability in bits. Higher entropy means more possible combinations and stronger security. Our tool calculates entropy based on character set size and password length.
Is my password data secure?
Absolutely! All password generation and analysis happens entirely in your browser using JavaScript. Your passwords never leave your device, ensuring complete privacy and security.
