Password

Generate strong random passwords.

A free password and passphrase generator with adjustable length, character sets, look-alike exclusion and batch output, plus a live entropy and strength readout. It uses the browser’s cryptographic RNG locally — passwords are never sent anywhere.

How to use

1. Switch between Random password and Passphrase.
2. Adjust length (or word count), character sets and separator options.
3. Enable “No look-alikes” to avoid O/0, l/1 and similar.
4. Check the strength bar and entropy, then copy; use the count slider to generate several at once.

FAQ

Are the generated passwords secure?

Yes. Passwords are generated locally with the browser’s cryptographically secure RNG (crypto.getRandomValues), are never transmitted, and disappear when you close the page.

What does the entropy (bits) mean?

Entropy measures how unpredictable a password is — more bits means harder to brute-force. As a rough guide, aim for 60+ bits for everyday accounts and more for critical ones.

Should I pick a random password or a passphrase?

Random passwords pack more entropy per character; passphrases are made of words, easier to remember, and handy when you have to type the secret by hand.
