Random Passphrase Generator
Independent word selection, so knowing one word tells you nothing about the next.
The difference between a 'passphrase' and a 'random passphrase' is whether the words are related. A phrase you invent — correct horse battery staple — is a sentence you made up, and sentences have grammar that shrinks the search space. Selecting words independently removes that structure.
This page defaults to five words, which sits at about 65 bits: enough for an email password, short enough to type on a phone keyboard.
How to use it
- Set the word count — five is a reasonable default.
- Generate a few and pick one you can picture; a phrase with a mental image sticks better.
- Store it in your password manager, then practise typing it once.
Independent selection vs. a phrase you invent
People asked to invent a phrase produce something with a subject, a verb and a familiar noun. An attacker who knows this can use a language model instead of brute force, which is why invented phrases test much weaker than their word count suggests.
Independent uniform selection has no grammar to exploit. The only structure is the one you choose — separator, capitalisation — and each of those is a published, countable option rather than a hidden predictability.

Frequently asked questions
Is a random passphrase better than a random password?
It depends on where you will type it. For a value you enter by hand on a TV or console, a passphrase is far more practical and still strong. For something stored in a manager, a random password is denser.
Can I use spaces instead of hyphens?
Yes, but check the destination system first — many trim or reject trailing and leading whitespace, and some collapse repeated spaces silently.
Does capitalising words help?
It adds a little, but less than people expect, because the choice is predictable. A fifth word is worth more.
