The famous XKCD comic “Password Strength” illustrated how a string of four random common words — like correct horse battery staple — can be both easier to remember and far more secure than a short, complicated jumble of letters, numbers, and symbols. Our XKCD password generator uses a curated dictionary of thousands of common English words, picking them at random so the resulting passphrase is unpredictable. Because the words are common and the combination is random, the phrase sticks in your mind while offering excellent entropy.
Unlike typical random word password tools, this generator allows you to adjust the number of words (4 by default) and optionally add a digit or symbol for extra complexity. The strength indicator updates instantly: a 4‑word passphrase from a 7000‑word list offers roughly 51 bits of entropy — that’s strong. Adding a digit or symbol increases it further. The result is a memorable password generator that helps you avoid the bad habit of reusing weak passwords.
Passphrases generated here are created entirely in your browser with no network calls. Combine them with a password manager for the best security: use the manager to store them, and use the passphrase as your master password or for sites you need to type manually. It’s the smart, human-friendly way to stay safe online.
