Passphrases use random words instead of random characters — making them easy to remember while remaining extremely secure. A 4-word passphrase has more entropy than most 10-character random passwords.
Master passwords for password managers, full-disk encryption, and any password you must memorize. Passphrases balance human memorability with cryptographic strength.

How to Generate a Random Passphrase — Memorable & Secure
- Open the Password Generator tool
- Switch to "Passphrase" mode
- Choose 4-6 words for your desired security level
- Select a separator (hyphen, space, or dot)
- Click "Generate Passphrase"
- Memorize using a mental image or story connecting the words
Pro Tips
- 4 words from a 7,776-word list = ~51 bits of entropy (strong for most uses)
- 5 words = ~64 bits — recommended for master passwords
- Add a number or symbol between words for extra entropy if required
- Create a mental story linking the words for easy memorization
Frequently Asked Questions
Are passphrases more secure than passwords?
A 4-word random passphrase (~51 bits) is comparable to a random 8-character password. A 5-word passphrase (~64 bits) surpasses most 10-character passwords. The advantage is memorability.
How many words should a passphrase have?
4 words minimum for general use. 5 words for important accounts. 6 words for maximum security (master password, encryption key). Each word adds ~12.9 bits of entropy.
Can I modify the generated passphrase?
Adding your own modifications (capitalize a word, add a number) increases security further. But the random words alone provide the core entropy — don't replace them with predictable words.
What is a diceware passphrase?
Diceware uses physical dice rolls to select words from a 7,776-word list. Our tool uses cryptographic randomness (equivalent security) instead of physical dice for convenience.
