(1)Frequently Asked Questions
How are passwords generated?▼
Passwords are generated using the browser's cryptographically secure pseudo-random number generator (CSPRNG via window.crypto.getRandomValues). This ensures maximum entropy and unpredictability.
Are generated passwords saved or sent over the internet?▼
Never. The Password Generator runs 100% locally in your web browser. No passwords, options, or telemetry are ever sent to a server.
What is a good password length?▼
Security experts generally recommend at least 16 characters with a combination of uppercase letters, lowercase letters, numbers, and symbols. For critical accounts, 20+ characters or a 5-word passphrase provides virtually unbreakable security.
What is a memorable passphrase?▼
A passphrase combines multiple dictionary words separated by a hyphen or delimiter (e.g., "correct-horse-battery-staple"). It is much easier for humans to remember while still offering massive cryptographic entropy against brute-force attacks.
Can I generate multiple passwords at once?▼
Yes! Use the Bulk Generation panel to produce up to 100 secure passwords at once and copy or download them as a .txt file.
