Build memorable yet strong passphrases from random words.
Words are chosen locally with a secure random generator.
How do you generate a strong passphrase?
Words are selected at random from a built-in word list using a secure random generator, joined with your chosen separator. Each added word multiplies the number of possibilities, so more words mean exponentially greater strength; use at least four words for important accounts. Four random words such as "river-maple-orbit-clay7" are far easier to recall than a symbol string of similar strength.
Understanding your result
Each added word multiplies the number of possibilities. Use at least four words for important accounts.
Formula and method
Words are selected at random from a built-in word list using a secure random generator. More words mean exponentially more combinations and greater strength.
Assumptions and limitations
The generator assembles random words using a secure random generator in your browser; the words are never sent anywhere. It does not store, sync or manage the passphrases it creates, so you must save them yourself, ideally in a password manager. It also cannot judge whether a site's rules will accept a given passphrase format.
Worked example
Four random words such as “river-maple-orbit-clay7” are far easier to recall than a random symbol string of similar strength.
How to use this tool

About the Passphrase Generator
Passphrases combine several random words into something both strong and easy to remember — often more practical than a string of symbols.
Who should use this tool
For anyone who wants strong login credentials they can actually remember: people securing email, banking or password-manager master passwords, IT staff advising colleagues, and privacy-minded users tired of unmemorable symbol strings. If you would rather recall a few random words than a jumble of characters, this builds them for you.

Frequently asked questions
Are passphrases secure?
Yes, when they use enough truly random words. Four or more random words provide strong protection.
How many words should a passphrase have?
Use at least four random words for anything important. Each word you add multiplies the number of possible combinations, so length is what makes a passphrase hard to guess. Four or more genuinely random words gives strong protection while staying far easier to remember than an equivalent string of symbols.
Are the passphrases generated on my device or a server?
They are built entirely in your browser using a secure random generator, and the words are never sent anywhere. That means no one else, including this site, ever sees the passphrase you create. Once generated, save it somewhere safe such as a password manager, because the tool does not keep it.
