Free Passphrase Generator — Secure Word Passwords Online
Generate memorable yet secure passphrases from random words — easier to remember than random strings, impossible to guess.
How it works
Choose word count
Select 3–8 words. Four or more words gives excellent entropy for most use cases.
Set separator
Use hyphens, underscores, spaces, or any custom character between words.
Customise
Toggle capitalisation and a random number suffix to meet specific password policies.
Copy and save
Copy the passphrase instantly. Nothing is stored on any server.
Common use cases
Master password creation
A 5-word passphrase has ~65 bits of entropy — stronger than most random 12-char passwords yet far more memorable.
Wi-Fi passwords
Create a passphrase you can type on a TV remote or phone keyboard without frustration.
Shared credentials
Generate passphrases you can read aloud or write down for colleagues without transcription errors.
Low-friction security
Encourage strong passwords in teams that resist complexity by offering easy-to-type alternatives.
Frequently asked questions
Are passphrases as secure as random passwords?
A 4-word passphrase from a 2048-word list has ~44 bits of entropy — comparable to a random 8-char password. Adding more words or a number quickly surpasses most random passwords.
Is this generator truly random?
Yes. Word selection uses crypto.getRandomValues() — the browser's CSPRNG — not Math.random().
Where does the word list come from?
An embedded list of ~200 common English words is bundled directly in this page. No external requests are made.
Are my passphrases sent anywhere?
No. All generation runs in your browser. Nothing leaves your device.
Should I capitalise words?
Capitalising the first letter of each word adds character variety, which helps meet many password policies without reducing memorability.
Can I use this on mobile?
Yes — the tool is fully responsive and works on all modern mobile browsers.
