Generate a readable passphrase from a built-in word list and estimate its entropy.
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.
