Générer secure, memorable passphrases made of random words. Easier to remember than random characters, just as secure. Customize word count, separators, and options. Pure côté client — no data sent anywhere.
Passphrases are sequences of random words used as passwords. They are easier to remember than random character strings while being equally or more secure. The famous XKCD comic "Correct Horse Battery Staple" popularized this concept. A 4-word passphrase has about 44 bits of entropy, making it very difficult to crack through brute force.
A passphrase is a sequence of words used as a password. Unlike traditional passwords made of random characters (e.g., "Tr0ub4dor&3"), passphrases use random words (e.g., "correct-horse-battery-staple"). They are easier to remember and type while being just as secure.
A 4-word passphrase from a list of 7,000 words has about 44 bits of entropy. Ceci means it would take roughly 2^44 guesses to crack by brute force, which is computationally infeasible for most attackers. Adding a number or special character increases security further.
Les deux are secure if long enough. Passphrases are generally better for passwords you need to remember (like master passwords). Aléatoire passwords are better for accounts where you can use a password manager. Use what works best for your situation.
Non. Tout generation happens in your browser. Nothing is sent to any server. The words are selected randomly using your browser's cryptographically secure random number generator.
For most purposes, 4-5 words is sufficient. For high-security applications (like cryptocurrency wallets or master passwords), 6+ words is recommended. Chaque additional word exponentially increases the security.
