FAQ

Common Questions

Find answers to common questions about generating strong, cryptographically secure passwords locally.

How does this tool generate secure passwords?
It uses the browser's native Web Cryptography API (window.crypto.getRandomValues), which utilizes system entropy to generate cryptographically strong, unpredictable random numbers.
What is entropy and why does it matter?
Entropy measures the randomness and strength of a password in bits. Higher entropy makes the password significantly harder for automated brute-force attacks to guess.
What makes a password strong?
A strong password is long (12+ characters), includes a mix of uppercase and lowercase letters, numbers, and symbols, and avoids predictable words, patterns, or personal details.
Are the generated passwords stored or logged?
Absolutely not. The generator runs completely client-side in your browser's memory sandbox. Once you close the tab or refresh, the passwords disappear forever.
Can I generate multiple passwords in bulk?
Yes, the generator provides bulk password options, allowing you to generate several custom-length random keys simultaneously in a single session.
