What It Does

Passphrase Generator creates secure, memorable passphrases using the diceware method—instantly, in your browser. Perfect for:

  • Creating strong, memorable passwords
  • Generating secure passphrases for accounts
  • Improving online security with longer phrases

Diceware is a technique where you randomly select words from a special list (originally using dice rolls) to create a passphrase. Each word is chosen independently and at random, making the resulting passphrase both highly secure (hard to guess) and easy to remember. The more words you use, the stronger your passphrase becomes.

All generation happens in your browser for maximum privacy—no data ever leaves your device.
