Passphrase Generator
Generate memorable word-based passphrases with secure randomness.
Memorable, strong passphrases
A string of a few random common words is far easier to remember than a jumble of symbols, and just as hard to guess. This generator picks words from a built-in list using your browser’s secure random source and joins them into a passphrase.
Five random words give roughly 40-plus bits of entropy while staying memorable, and the tool shows the exact bit strength for the number of words you choose. Click generate for a fresh one any time.
Secure and private
It uses crypto.getRandomValues rather than a predictable generator, and the passphrase is created in your browser and never stored or uploaded.
Frequently Asked Questions
How are the words chosen?
Randomly from a built-in word list using crypto.getRandomValues, the browser’s cryptographically secure random source — not the predictable Math.random.
Why are word passphrases strong?
Length beats complexity: several random common words are easy to remember yet have high entropy, which the tool reports in bits.
Is the passphrase stored?
No. It is generated in your browser and never saved or transmitted. Regenerate as often as you like.
