Make something memorable.
Random words strung together are easier to remember than random characters — and just as strong. Generated in your browser, nothing sent anywhere.
Runs locally. Uses your browser's cryptographic random number generator. No passphrase you create here is ever transmitted, stored, or seen by anyone but you.
The built-in list is 435 common English words. For stronger passphrases, load the EFF Large Wordlist (7,776 words) or EFF Short Wordlist (1,296 words). Any plain-text file with one word per line works. Your list stays in memory for this session only.
Strong enough to protect you. Simple enough to remember.
Built for memory
Five random words are far easier to recall than a string of random characters — and equally hard to crack when chosen randomly.
Entropy is what matters
Five words from a 435-word list gives ~44 bits of entropy. Load the EFF Large Wordlist and that jumps to ~65 bits — stronger than most complex passwords people actually use.
Best for things you type
Disk encryption, password manager master password, anything you can't copy-paste. Passphrases are made for these situations.
