Password generator

Generate strong random passwords, or passphrases made of real words that you can actually remember. Uses your browser's cryptographic random number generator, and shows the strength in bits so you can see why five words beat eight characters.

How it works

1. Choose random characters or words.
2. Set the length and options.
3. Copy the password into your password manager.

Questions about password generator

Is a passphrase really strong?

Five random words from this list give about 39 bits; add a number and capital letters for more. A 16-character random password is stronger still, but a passphrase is far easier to type and remember.

Is the password sent anywhere?

No. It is generated on your device and the page makes no network requests.
