Memorable Passphrase Generator
Generate a passphrase built from real random words instead of a jumble of symbols — strong enough for real security, and actually memorable.

How the Memorable Passphrase Generator works
This follows the same logic popularized by the classic XKCD 'correct horse battery staple' comic: a passphrase built from several random dictionary words carries more entropy — and is far easier to remember and type — than a shorter string of random special characters, because each additional random word multiplies the number of possible combinations by the size of the word list.
The optional number and symbol are inserted at a random position within the passphrase (not always appended at the end), since attackers are well aware that 'word-word-word-1!' is a common pattern and check it early — shuffling the position removes that predictable structure.
The entropy estimate shown is a real calculation based on your exact settings: word count, dictionary size (301 words), and whether a number and/or symbol are included — not a made-up number.
How to use it
Frequently asked questions
Is this actually more secure than a random character password?
For the same length, a true random-character password has more entropy per character — but passphrases let you comfortably use far more total characters since they're easy to remember, which usually results in equal or greater total entropy in practice.
How many words should I use?
4 words is a reasonable baseline for most accounts; use 6 or more words for something highly sensitive like a password manager's master password.
Why include a number or symbol at all if words are already strong?
Some sites require a number or symbol by policy — this lets you satisfy that requirement without giving up the memorability of a word-based passphrase.
