This page is designed to help you find out whether Passphrase.website is good and if it is the right choice for you.
Passphrase.website is a free browser-based passphrase generator and strength checker. No account is required to use the tool.
Passphrases are generated locally using the Web Crypto API. The Classic option uses a locally stored copy of EFF's 7,776-word list; themed word lists are also available. Customize length, capitalization, numbers and symbols, and generate one, five or ten results at a time.
Generated results show entropy based on the actual word pools and an estimated cracking time. These are estimates, not security guarantees, and themed lists have different entropy from the Classic list. For independently selected Classic words, six words provide about 77.5 bits of word-selection entropy.
Generated passphrases and text entered in the strength checker are not sent to the server or stored there. Anonymous activity records include timestamps, action type and, for generation, count and selected options—not the passphrases. The site also provides practical guides to passphrase length, online-generator safety, passkeys and account security. See its Privacy Policy for contact-form data, advertising and other site data practices.

Passphrase Strength Checker
Test the strength of your existing passphrase or any custom phrase
Passphrase.website is a free, privacy-first passphrase generator built for people who want strong security without the headache of remembering random gibberish. Unlike most online password tools, every passphrase here is generated entirely inside your browser using the Web Crypto API — the same cryptographically secure randomness that protects HTTPS connections. Your passphrases are never sent to a server, logged, or stored. We also show the real entropy in bits and a realistic time-to-crack estimate for every result, so you can see exactly how strong your passphrase is instead of guessing from a vague colored bar. Choose the Classic (EFF wordlist) theme for maximum strength — 7,776 words, the same list security professionals recommend — or pick a themed list for something easier to remember. Customize length, capitalization, numbers and symbols to match any site's rules, then copy and go. No account, no paywall — just secure passphrases you can actually remember.
