Word Password Generator: Passwords Made of Random Words

A word password — also called a passphrase — strings several random words together into a single password that is both highly secure and easy to remember, like "Timber-Canoe-Frozen-Maple-97". This word password generator picks each word from a curated list using cryptographic randomness, so every combination is unique and unguessable. A 4-5 word password provides over 50 bits of entropy while staying human-friendly. Word-based passwords are ideal for master passwords, device logins, WiFi keys, and any situation where you need to type your password by hand.

Key facts

  • A word-based password draws each word at random from a fixed list, so its strength comes from the word count — not from the words being unusual.
  • Each word from this generator's list adds roughly 11–13 bits of entropy; 5 words gives about 64 bits.
  • A 5-word password is roughly as hard to crack as a 10-character random password, but far easier to remember and type.
  • Word passwords you invent yourself are much weaker than generated ones — human word choice is highly predictable.
  • Every password here is generated in your browser using the Web Crypto API. Nothing is sent to any server.

What is a passphrase, or word password?

A passphrase is a password made of multiple random words strung together, like "Timber-Canoe-Frozen-Maple-97". People also search for this as a "word password", a "password based on words", or a "memorable password" — they all describe the same thing. Unlike traditional passwords, word passwords are designed to be memorized and typed by humans while maintaining high entropy. The concept was popularized by Diceware, a method where you roll physical dice to select words from a list. This generator applies the same principle using cryptographic randomness instead of dice, producing results that are statistically equivalent in security.

How secure are passphrases?

Security depends on the word count and list size. This generator uses a curated list of common English words. Each word adds approximately 11-13 bits of entropy depending on the list size. A 4-word passphrase provides about 50 bits of entropy — adequate for low-value accounts. A 5-word passphrase gives about 64 bits — good for most purposes. For high-value targets like your password manager vault, use 6 or more words (77+ bits). Adding a number and capitalizing words further increases entropy by several bits.

Passphrase vs password: when to use each

Use a passphrase when you need to type the password from memory: your computer login, phone lock screen, password manager master password, WiFi access, or full-disk encryption. Use a random character password when you'll paste it from a password manager — this maximizes entropy per character. The ideal setup is a strong passphrase for your password manager vault, with unique random passwords for every other account stored inside it.

Tips for stronger passphrases

Avoid famous quotes, song lyrics, or book titles — attackers build dictionaries from cultural references. Always use randomly generated word combinations, not phrases you invent. Use at least 4 words; 5-6 is better. Add a number or symbol between words for extra entropy. Capitalize at least one word. Never reuse a passphrase across accounts. Consider adding one intentional misspelling (e.g., "Timbr" instead of "Timber") for an additional layer of unpredictability that defeats dictionary attacks.

Can I generate a password from my own words?

This generator does not take your own words as input, and that is deliberate. The security of a word password comes from each word being chosen at random from a known list — that is what makes the number of possible combinations calculable and enormous. Words you supply yourself are drawn from a much smaller, highly predictable pool: names, pets, hobbies, places you have lived. An attacker who knows anything about you can narrow that pool dramatically, and password-cracking tools already combine common personal terms automatically. If you want a password you can remember, generate one here and memorise it — five random words are easier to retain than most people expect, and vastly stronger than five words you picked.

How many words make a 12-character password?

Word passwords are measured in words, not characters, but the two line up roughly as follows: three short words with separators land around 12-16 characters, four words around 20-25, and five words around 28-32. If a site caps you at 12 characters, a word password is usually the wrong tool — that limit is too short to fit enough words, and a random character password will give you more entropy in the space available. Use the character-based generators for length-capped fields, and word passwords wherever you can use 20 characters or more.

Frequently asked questions

What is a word password generator?
A word password generator builds a password by picking several words at random from a fixed list and joining them together, for example "Timber-Canoe-Frozen-Maple-97". It is also called a passphrase generator or a diceware generator. Because the words are chosen by a cryptographic random number generator rather than by a person, the result is both easy to remember and hard to guess. This generator runs entirely in your browser — no word list lookup or password ever reaches a server.
Can I generate a password based on my own words?
No, and that is intentional. A word password is only strong because each word is drawn at random from a known list, which makes the number of possible combinations calculable and very large. Words you choose yourself come from a small, predictable pool — names, pets, places, hobbies — that cracking tools already target. If you want a memorable password, generate a random one here and learn it rather than assembling one from words that mean something to you.
Are passphrases more secure than passwords?
They can be. A 5-word passphrase has roughly 64 bits of entropy — comparable to a 10-character random password. The advantage is memorability: you can remember "Timber-Canoe-Frozen-Maple-97" but not "kX9#mR2$pL". For maximum security per character, random passwords win. For something you need to type and remember, passphrases are superior.
How many words should my passphrase have?
At minimum 4 words for basic accounts. Use 5 words for important accounts (email, banking). Use 6+ words for your password manager master password or full-disk encryption. Each additional word roughly doubles the number of possible combinations.
Can I modify the generated passphrase?
You can, but be careful. Adding a word or number increases security. Removing a word decreases it. Replacing a random word with a personally meaningful one (like a pet's name) can weaken the passphrase if an attacker knows you.
What separator should I use between words?
Any separator works. Hyphens are popular because they're easy to type. Spaces work if the system allows them. The separator itself adds minimal entropy — it's the word count that matters most.
