Passphrase generator

A handful of random words beats a short password full of symbols, and you stand a chance of remembering it. Generate one here, entirely in your own browser.

How to read the result

  • What entropy tells you

    Entropy measures how many guesses an attacker would need. Each extra word adds far more than swapping a letter for a symbol does, which is why length wins.

  • Where it is generated

    In your browser, using the built-in cryptographic random generator. Nothing is sent to us, nothing is logged, and nothing is stored. Close the tab and it is gone.

  • Use a password manager

    Remember one strong passphrase for the manager itself, and let it generate and store the rest. Never reuse a passphrase across accounts.
