Passphrase Generator: Memorable and Ultra-Secure Word Passwords
Passphrases (word passwords like 'correct horse battery staple') offer more security AND more memorability than complex passwords. A 7-word passphrase from a 7776-word dictionary has 90 bits of entropy — practically unbreakable — and is easy to remember.
Our generator uses the EFF long wordlist (7776 words selected for memorability) applying the Diceware method: each word chosen by 5 dice rolls (random cryptographic simulation). Options to add numbers, symbols, or capitals if you need to comply with password policies.
Ideal for master passwords of password managers, disk encryption (BitLocker, FileVault), or SSH key protection. Anywhere you need high entropy with memorable strings.
How does it work?
- 1Select number of words
5 words = 65 bits (good). 6 = 77 bits (very good). 7 = 90 bits (excellent, recommended).
- 2Choose separator
Hyphens (correct-horse-battery-staple), spaces, camelCase, or none. Hyphens improve readability.
- 3Copy the passphrase
Store in your password manager and start using. Consider practicing it several times to memorize it.
Frequently Asked Questions
The famous XKCD example has ~44 bits of entropy (4 words × 11 bits each in short dictionary). It's stronger than 'Tr0ub4dor&3' (28 bits), but for 2026 we recommend 6-7 words from long dictionary (77-90 bits) for offline attacks.
Create a mental story linking the words. Words are more memorable than random characters because our brain evolved to remember narratives. In a week of daily use, you'll have it memorized permanently.
Only if the service requires it (many demand at least 1 number, 1 symbol). Add them at natural points (correct-horse-3-battery-staple!) without breaking memorability. Adding a random symbol at the end is enough for most policies.
