Passphrase Generator
Generates passphrases from a 256-word list and passwords from a character set, using your browser's cryptographic random source. The entropy shown is the real figure, not an estimate.
Nothing leaves your browser
This tool runs entirely in the page you are looking at. What you enter is never sent to us or to anyone else, is not stored, and disappears when you close the tab. It also never fetches anything on your behalf. It works only on what you give it.
This is a generator, not a strength checker. A checker invites you to type a password you actually use into a web page, and that is a habit worth not building — even when, as here, nothing is sent anywhere.
Assuming one trillion guesses per second — an offline attack against a fast hash, not someone typing at a login form. A friendlier assumption would flatter every result on this page.
