Free passphrase generator for strong, memorable logins.
Create secure, diceware-style passphrases made from random words. Get the best of both worlds: high entropy like a strong password, but far easier to remember and type.
Memorable, but still hard to crack
Instead of short, complex strings, passphrases use several random words combined together. This can give you very high entropy while remaining something a human can actually remember — especially for master passwords or important logins.
- Choose how many words you want in your passphrase.
- Select separators, capitalization, and optional numbers/symbols.
- Generate random, diceware-style passphrases instantly.
- Copy with one click and save in your password manager.
Tip: Use long passphrases (at least 5-7 words) for master passwords, email, and other high-value accounts, and store them safely in a password manager.

Create a random, diceware-style passphrase locally in your browser. Adjust the number of words and formatting until you're happy with it.

Why use passphrases?
A modern alternative to traditional passwords.
Random strings like pR7!f9$Q are strong but impossible to remember. Random passphrases are different: they combine multiple unrelated words, which your brain handles much better.
1. High entropy from word combinations
Each extra random word multiplies the number of possible combinations. With enough words, passphrases become extremely hard to brute-force.
2. Easier to remember
Phrases like “river-window-orange-planet” are far easier to recall than a jumble of symbols, even though they may offer similar or better security.
3. Great for master passwords
Long, random passphrases are ideal for your password manager's master password or any login you type regularly and really cannot afford to lose.
Passphrase best practices
Get the most security out of your passphrases.
Passphrases are powerful, but only when they're truly random and long enough. Avoid turning them back into predictable sentences.
Don't use meaningful phrases
Avoid quotes, song lyrics, or phrases you like. Attackers target common sentences and public phrases in real-world cracking tools.
Use enough random words
Three or four words might be okay for low-risk accounts, but important accounts should use at least 5-7 truly random words.
Add variety if needed
For extra strength, you can mix in capitalization, digits, or symbols — but don't overcomplicate things if it harms memorability.
Store where it's safe
Even a strong passphrase won't help if you lose it. For most people, a secure password manager is the best place to store passphrases you don't want to memorize.
FAQ
Passphrase generator questions, answered.
Learn how passphrases compare to traditional passwords and how to use them safely in your security setup.
How is this different from a normal password generator?
Traditional generators create random characters; this one creates random words. Both can be very strong, but passphrases are often easier to type and remember, especially for long-term use.
Is this like diceware passphrases?
Yes — it follows the same core idea: randomly selecting words from a list to build a high-entropy phrase. Classic diceware uses physical dice; here, we use secure randomness in your browser.
Do you store the passphrases I generate?
No. Passphrases are generated locally in your browser and are never sent to our servers. Once you close the page, they're gone unless you saved them.
Are passphrases always more secure?
Not automatically. Strength comes from randomness and length. A truly random 6+ word passphrase is generally much stronger than a short, memorable sentence you came up with yourself.
