About this tool
A passphrase is a password made of several random words, like Linen-Quartz-Core-Shade-Hound. It is much easier to remember and type than a jumble of symbols, yet very hard to guess when the words are chosen at random. This generator picks words with your browser's cryptographically secure random number generator and shows the strength in bits of entropy.
How to use Passphrase Generator
- Choose how many words to use; five or more is strong for most accounts.
- Pick a separator and whether to capitalize words or add a number and a symbol.
- Copy your passphrase, or generate a list to choose from.
Worked example
A five-word passphrase from a 1,000-word list has about 50 bits of entropy. At 10 billion guesses a second, it would take on average years to crack, and every extra word multiplies that by about 1,000.
Are passphrases better than passwords?
A long random passphrase is as strong as a complex password but much easier to remember and type, which is why many security experts recommend them.
How many words should I use?
Five or six random words suit most accounts. Use seven or more for very sensitive accounts like a password manager's master password.
Is my passphrase stored?
No. It is generated in your browser and never sent to our server.
