Fresh wordlists for all your passphrase-creation needs. Use these wordlists to create strong, secure passphrases, either with dice or a password manager/generator.
- Made up of common words found in (English) Wikipedia and Google Books
- Uniquely decodable, and thus safe to combine words in passphrases without a delimiter
- Free of profane words, abbreviations, and British spellings
- Available in a variety of lengths for different use-cases
NOTE: These lists are occasionally edited. If you want a static, unchanging copy of any of the word lists, feel free to download the lists as they are currently, download the latest tag/release, or fork this repository at any time. See licensing information below.

The Orchard Street Diceware List is our version of the classic Diceware list. With this list, you can use dice to create a secure passphrase). This list's 7,776 words gives a traditional 12.925 bits of entropy per word, same as the EFF long word list.
This list is also available without corresponding dice roll numbers prepended.
List length : 7776 words
Mean word length : 7.05 characters
Length of shortest word : 3 characters (add)
Length of longest word : 10 characters (worthwhile)
Free of prefix words? : false
Uniquely decodable? : true
Entropy per word : 12.925 bits
Efficiency per character : 1.832 bits

Orchard Street Alpha and Orchard Street QWERTY lists both have 1,296 words and are optimized for inputting resulting passphrases into devices like smart TVs or video game consoles. Each word gives a passphrase an additional 10.34 bits of entropy.
The difference between these two lists are which keyboard layout they are optimized for. Use the Alpha list if your device's keyboard is laid out alphabetically; use the QWERTY list if it is closer to the QWERTY layout.
List length : 1296 words
Mean word length : 4.12 characters
Length of shortest word : 3 characters (add)
Length of longest word : 7 characters (stopped)
Free of prefix words? : false
Uniquely decodable? : true
Entropy per word : 10.340 bits
Efficiency per character : 2.509 bits
Above brute force line? : true
Mean edit distance : 4.043
