Passphrase Generator
Create strong, memorable passphrases from random common words. A passphrase like correct horse battery staple is easy to type and hard to crack.

- Click Generate passphrase. Each passphrase is built from truly random picks (your browser's secure random generator), never the same twice.
- Click Copy passphrase and use it as a password anywhere.
Note
The strength meter shows estimated guessing difficulty based on the number of words and the word list size (671 common words). Four random words plus a digit give about 41 bits of entropy — strong enough for most accounts — and five or more words are suitable for master passwords. Avoid using a generated passphrase on multiple sites, and store important ones in a password manager.
Frequently Asked Questions (FAQ)
What is a passphrase?
Several random common words joined together, like correct horse battery staple. It is easy to type and remember, yet hard to crack.
What can I customize?
The number of words (3 to 8), the separator (space, dash, underscore and more), plus options to capitalize, add a number and show a strength rating.
Why use a passphrase instead of a random password?
A string of random words is easier to remember and type than a jumble of characters, while still being hard to guess when it is long enough.
Are my passphrases kept private?
Yes. Everything runs in your browser, so generated passphrases never leave your device.
