Frequently Asked Questions

How long should a strong password be?

Security experts recommend at least 16 characters for important accounts. Longer passwords are exponentially harder to crack — a 20-character random password is essentially unbreakable with current technology. If a site caps password length at 8 or 10 characters, use the maximum allowed and include a mix of all character types.

Is it safe to generate passwords in a browser tool?

Yes — this generator uses the browser's built-in cryptographic random number generator (window.crypto.getRandomValues), which is designed specifically for security-sensitive applications. No data is sent to any server, and nothing is logged or stored. The password exists only in your browser tab.

Should I use a password manager with generated passwords?

Absolutely. Strong random passwords are difficult to remember by design — that's the point. A password manager (like Bitwarden, 1Password, or KeePass) stores them securely and autofills them, so you only need to remember one strong master password.

What makes a password strong?

Length is the most important factor — each additional character multiplies the number of possible combinations. After length, using a mix of uppercase letters, lowercase letters, numbers, and symbols increases complexity. Avoid dictionary words, names, dates, and predictable patterns even if they seem clever.

Can I generate multiple passwords at once?

You can click Generate repeatedly to create as many passwords as you need. Each click produces a completely new random password — previous passwords are not stored anywhere, so copy each one to your password manager before generating the next.
