About Password Generator
Password Generator is a free, private tool by Digital Heroes that runs entirely in your web browser. It uses your device's cryptographically secure RNG (crypto.getRandomValues), never the weak Math.random. Every password is generated locally. Nothing is uploaded to a server, and nothing is stored after you close the tab.
Choose between random character passwords (up to 64 characters, with uppercase, lowercase, digits, and symbols) and passphrases made from real words joined by a separator of your choice. A live strength meter shows the estimated entropy in bits so you always know how secure your result is.
Frequently asked questions
Is Password Generator free?
Yes. Password Generator is completely free for everyone. No sign-up, no account, and no usage limits.
Is it private? Are my passwords sent anywhere?
No. Everything runs in your browser on your own device. No passwords are transmitted to a server and nothing is logged or stored. Close the tab and the passwords are gone.
What is the difference between Random and Passphrase mode?
Random mode produces a string of characters from a pool you define (letters, digits, symbols). It is maximally compact and hard to crack. Passphrase mode produces several real words joined by a separator. Passphrases are longer in characters but much easier to type and remember, and still deliver strong entropy from a large word list.
What does the entropy number mean?
Entropy in bits measures how many guesses an attacker would need on average. 60+ bits is considered fair for most accounts. 90+ bits is excellent for sensitive accounts. The meter updates live as you change options.
Does it work offline?
Yes. Once the page has loaded, the tool keeps working with no internet connection. The word list and all logic are bundled in the page.
Do I need to install anything or create an account?
No. Just open the page and start using it. No installation and no account are required.
