WHY USE IT
Passwords made of words
A passphrase strings together several randomly chosen words, such as “cedar-orbit-lantern-frost”. It is far easier to read, type and say out loud than a jumble of symbols, which makes it a good choice for the few secrets you have to enter by hand.

HOW TO USE IT
Passphrase Generator in three steps
1
Open the Passphrase tab
Switch the generator to “Passphrase” to create word-based secrets instead of random characters.
2
Generate until you like it
Press Space or Enter for a new set of words. Never edit the words to make them “nicer”; that removes randomness.
3
Save it safely
Copy it into your password manager, or memorise it if it protects the manager itself.
Why passphrases work
The strength of a passphrase comes from the number of possible word combinations, not from clever spelling. It depends on two things: how many words are in the list it is drawn from, and how many words you use.
With a large list such as the EFF’s 7,776-word dice list, each word adds about 12.9 bits of entropy, so six words gives roughly 77 bits. The words must be chosen randomly; a phrase you pick yourself, like a song lyric, is far weaker.
Passphrase or random password?
Both are secure when generated randomly. Choose based on how you will use it:
Passphrase: master passwords, device logins, Wi-Fi keys and anything you type by hand.
Random password: everything stored in a password manager, where length costs you nothing.
PIN: only where a site or device demands digits, and ideally combined with another factor.
Tips for a stronger passphrase
Use more words for higher-value accounts; each extra word multiplies the combinations.
Keep the words exactly as generated. Do not swap in your favourite words.
Never reuse a passphrase across accounts.
Enable two-factor authentication on the account it protects.

Pick the right generator for the job
Use a unique secret for every account and store it in a reputable password manager.
Yes, when the words are chosen randomly from a large list and you use enough of them. Strength grows with every word you add.
How many words should a passphrase have?
Use at least five or six words from a large word list for important accounts. More words are stronger and only slightly longer to type.
Can I make up my own passphrase?
It is much weaker. People pick predictable words and phrases. Let the generator choose for you.
Is a passphrase better than a password?
Not inherently. A random 16-character password and a long random passphrase can both be very strong. Passphrases are simply easier for humans to type and remember.
Where are the words chosen?
In your browser, using the Web Crypto API. Nothing is sent to a server.
Should I use a passphrase for my password manager?
Yes. A long random passphrase is one of the best choices for a master password because you must type it from memory.
