Password & passphrase generator
Make strong random passwords or memorable diceware passphrases. Generated in your browser, never sent anywhere.
Is it safe?
Yes. Passwords are generated on your device with crypto.getRandomValues, the browser's cryptographic random generator, using rejection sampling so every character is equally likely. Nothing is sent to our server, logged or stored, and the page works offline once loaded.
Password or passphrase?
- Random passwords are best for anything a password manager fills in for you. 20 characters from all sets is about 130 bits.
- Passphrases are easier to type and remember: use them for your password manager's master password, disk encryption or your computer login. Six words from the EFF diceware list give about 77 bits.
- Never reuse a password, and turn on two-factor authentication or passkeys where you can.
