Generate high-entropy random phrases that are easy to remember but impossible for computers to hack. The security standard for master passwords in 2026.
A Passphrase is a sequence of random words. While traditional passwords like P@ssw0rd12! are hard to remember and easy for modern AI tools to crack, a phrase like correct-horse-battery-staple creates a massive number of combinations, making brute force attacks mathematically impossible.
Your security is our priority. We use the window.crypto.getRandomValues() API to generate true cryptographic randomness based on your device hardware. Unlike other tools, your words are never sent to our server, stored in a database, or tracked. This tool even works offline.
Entropy measures the unpredictability of your secret. Every random word you add exponentially increases the bits of entropy. According to NIST guidelines:
The best passphrases are random, long and unique. They should not contain quotes, song lyrics, names, birthdays or anything personally memorable. If you want to validate an existing password, use our password strength checker. If you want to reduce breach exposure, combine unique passphrases with our email breach checker and review our guide on why reusing passwords is dangerous.
A long password made of several random words. It is often easier to remember than a short random string with symbols and can be very strong if random.
Yes if words are truly random and not famous phrases. This tool uses random words from a local list and browser cryptography.
No. Generation happens in your browser with Web Crypto; nothing is sent to GenerarPassword servers.
You choose 4–8 words in the selector. Regenerate until you like the result, then copy it to your password manager.
Separators make copying clear. Some sites allow spaces or hyphens in passwords; check each service rules.
No. Each account should have a unique secret so one leak does not unlock others.
Both can be secure if long and unique. Passphrases help master passwords; random passwords plus a manager fit most logins.
Yes. After the page loads you can generate passphrases without a network connection.
