What makes a password strong

A strong password is long and unpredictable. Length matters more than complexity: each extra character multiplies the number of guesses an attacker needs. Mixing character types (uppercase, lowercase, numbers, and symbols) widens the pool further. This generator uses your browser's cryptographic random number generator, so every password is genuinely unpredictable — and because it all runs on your device, your password is never sent over the network.

The best long-term habit is a unique password for every account, kept in a password manager. That way you get maximum-strength passwords without having to memorise any of them.

FAQ

Frequently asked questions

Are these passwords safe to use?

Yes. Passwords are generated locally using your browser's cryptographically secure random number generator (crypto.getRandomValues). Nothing is transmitted, logged, or stored on any server.

How long should my password be?

For most accounts, 16 characters with a mix of upper and lowercase letters, numbers, and symbols is a strong choice. For high-value accounts, use 20+ characters or a passphrase.

What does 'exclude ambiguous characters' do?

It removes characters that are easy to confuse when typing or reading aloud — like the letter O and the number 0, or the letter l and the number 1. Useful when a password will be typed by hand.

Should I reuse a generated password?

No. Use a unique password for every account and store them in a password manager so you never have to remember or reuse them.
