Enter the example value or paste your own input, choose the mode when one is available, and read the first result card for the direct answer. The output area gives a copyable block for code reviews, documentation, API tests, classwork or troubleshooting notes.

What the result means

Passphrases are easier to type than random symbol strings while still offering a large search space when enough words are used.

What is not included

The built-in word list is compact for browser use. Use a full diceware list for formal policy requirements.

Privacy note

The calculation runs in your browser. Avoid pasting production secrets, credentials, private keys, customer data or regulated personal data unless your own policy allows browser-based tools.
