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
- Switch between Random password and Passphrase.
- Adjust length (or word count), character sets and separator options.
- Enable “No look-alikes” to avoid O/0, l/1 and similar.
- 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.
