Strong Passphrase Generator
Create passphrases that are both strong and easy to remember. A passphrase built from several random words is far easier to recall than a scramble of symbols, yet stringing enough unrelated words together produces plenty of entropy to resist guessing. This generator picks words at random from a large list and joins them with a separator you choose, with options to capitalize each word and append a number for sites that demand one. You control the word count, so you can trade a little length for a lot of extra strength. Each generated phrase copies with a click. The words are chosen using the browser secure random source and nothing is transmitted, so your passphrase is created entirely on your own device.
How to use Strong Passphrase Generator
- Set the number of words.
- Choose your separator, capitalization and numbers.
- Click generate.
- Copy the passphrase.
