Generate strong passphrases built from everyday words — the security of random, the friendliness of memorable.
Strong passwords are hard to remember, and remembered passwords are too weak. The solution? Passphrases: four or five random common words that are mathematically strong but human-friendly. This generator builds them instantly — with optional numbers and symbols — and shows you why they beat the passwords you are used to.
Everything you get with this tool — free, unlimited and right in your browser.
Four or five random common words produce passphrases that are hard to crack and easy to remember.
See the estimated entropy and strength of every passphrase, with clear labels you can trust.
Boost complexity with a number or symbol between words when a site demands special characters.
Generate a list of passphrases at once — pick your favourite and keep it in your password manager.
Get started in a few simple steps.
Pick 4 or 5 words — more words mean more strength while staying memorable.
Toggle numbers or symbols between words to satisfy sites that require special characters.
Check the entropy rating — the higher, the harder to crack.
Copy your passphrase into your password manager or a secure note.
Pro tips to get the most out of this tool.
A 5-word passphrase has far more combinations than a typical 10-character password — and it is actually memorable.
A strong passphrase is useless if it secures two accounts. Use a different one everywhere.
Memorable is great, but a password manager keeps hundreds of unique passphrases organised.
The generator picks common words randomly — never build passphrases from names, birthdays or pets.

Yes — free, unlimited and private. Generation happens locally in your browser; nothing is stored or sent.
Each word adds many possibilities. Five words from a 10,000-word list create more combinations than most 10-character passwords.
Most services accept spaces and longer passwords. If a site limits length, use the hyphenated or symbol version.
Yes — even a memorable passphrase is better stored and managed with unique ones for every account.
