Frequently Asked Questions

What is the difference between a passphrase and a password?
A password is typically a single string of random characters (e.g., xK9#mP2v), while a passphrase is made up of multiple random words joined together (e.g., sakura-hikari-kaze-yama). Passphrases are generally easier to remember while maintaining strong security through their length and the randomness of word selection. A 5-word passphrase can have over 50 bits of entropy, comparable to a complex 10-character password.
What are the advantages of Japanese and Chinese passphrases?
Japanese romaji and Chinese pinyin passphrases use different word pools from English, making them harder to crack with standard dictionary attacks that typically target English words. They are also memorable for Japanese or Chinese speakers and can be typed on standard keyboards. Chinese entries show hanzi glosses to make the pinyin easier to recognize.
How many words should I use?
We recommend at least 5 words for general use and 7 or more words for high-security accounts. Each additional word significantly increases the entropy and crack resistance of your passphrase. A 5-word passphrase from our English list provides about 54 bits of entropy, while 7 words provides about 75 bits. Adding capitalization, numbers, or symbols further increases security.
