What is Diceware?
Diceware is a method of creating secure passwords based on the use of dice. This technique is particularly effective for generating random and hard-to-crack passwords consisting of a large number of words. The use of diceware is a common practice among IT professionals and security experts who place the highest value on cybersecurity.
How does diceware work?
In the diceware method, the user takes a certain number of dice (typically five) and rolls them to achieve a combination of numbers. Each combination corresponds to a specific word in a list known as a Diceware word list. For example, the number 12345 could correspond to the word "cat". By stringing several words together, a strong password is created.
The steps to create a diceware password
- Count the number of words you want in your password (at least 6 is recommended).
- Roll the desired number of five-sided dice for each word.
- Look up the number combination you rolled in the Diceware word list.
- Repeat steps 2-3 until you have all the words for your password.
- Put the words together (optional: add special characters to increase security).
The advantages of Diceware
There are many advantages to using the Diceware method. One of the main advantages is user-friendliness, as the method is easy to learn and implement. Diceware also generates passwords that are difficult to guess or crack using brute force methods, making it a popular choice for protecting sensitive information.
Why choose Diceware?
- High security: The random combination of words makes it extremely difficult for hackers to crack the password.
- Simplicity: Compared to complex, random character strings, it is easier for people to memorise words.
- Flexibility: You can easily customise the length of your password by choosing more or fewer words.
The Diceware wordbook
The Diceware word book is an essential part of this method. It contains a list of words that have been randomly selected to ensure that the generated passwords are strong and unpredictable. Each word is linked to a combination of five digits, so that each combination of numbers represents a unique word. You can find multiple versions of this word list to ensure that you use a list that suits your needs.
Illustrative example on the topic: Diceware
Imagine an employee of a large company is given the task of creating a new password for their access to the company network. Instead of choosing a typical password such as "password123", he decides to use the diceware method. He rolls the dice five times and gets the number combination 54321. He looks up this result in the Diceware word list, where he finds the word "flower". He repeats this process a total of six times and finally obtains the words "flower", "table", "whale", "star", "car" and "luck". His final password is therefore "FlowerTableWhaleStarCarLuck". By combining six random words, he has created a secure, memorable password that is much less susceptible to attack than a common password.
Conclusion
The Diceware method is an excellent way to create secure, easy-to-remember passwords. By combining several random words from the Diceware word list, you prevent passwords from being easily guessed, protecting personal and business data from unauthorised access. If you're looking for an effective way to improve your cybersecurity, Diceware is definitely worth a try.

Frequently asked questions
The diceware method offers several advantages that make it a favoured choice for password security. Firstly, it allows the creation of passwords consisting of multiple random words, making them harder to guess. Secondly, these passwords are easier to remember than complex alphanumeric combinations. In addition, the method is easy to learn and requires no specialised technical knowledge, making it accessible to everyone.
Diceware passwords are considered very secure as they consist of a combination of words that are randomly selected by rolling dice. Compared to conventional passwords, which often contain simple patterns or personal information, diceware passwords are much harder to crack. The use of an extensive word list increases complexity and makes brute force attacks almost impossible, making it one of the most secure methods of password creation.
For a secure Diceware password, it is recommended to use at least six words. This number ensures sufficient length and significantly increases the security of the password. The more words you combine, the more difficult it will be for attackers to guess the password or crack it using brute force methods. Some experts even recommend using even more words to further increase security.
Yes, Diceware can be used in different languages as long as a corresponding word list is available. There are special Diceware word lists for many languages that are designed to provide a variety of words to ensure the security of the generated passwords. Using a word list in the desired language allows users to create passwords that are both secure and easier to remember.
To make Diceware passwords even more secure, you can insert special characters or numbers between the words to increase the complexity. Another option is to use a passphrase, where you define a certain structure or pattern for the selection of words. It is also advisable to change your passwords regularly and use a password manager to ensure the security of your sensitive information.
The Diceware word list is available online on various websites that deal with password security and cybersecurity. You can visit the official Diceware page to download the latest and most recommended word lists. There are also variants of these lists that are customised to specific needs or languages. Be sure to choose a trusted source to ensure the integrity of the word list.
