If it is not enabled, you can use the Synaptic Package Manager or the following command lines sudo add-apt repository universe
Online password generator from words software#
The software described is available via the Ubuntu repository Universe.
It should be noted here that Ubuntu's password functions for user accounts do provide some means of enforcing strong passwords for user accounts, but there are cases, and applications where the strength of the password cannot be enforced in this manner, and so this guide exists to help the user generate acceptable strong passwords. Read the available information, take some time to think about it, and use the method that you find is the best one for your purposes. If you wish to study APG and 'xkcdpass' further, you may find information at the Resources section of this guide. Also 'xkcdpass' is available via the repository Universe. Not only does APG generate passwords, it will generate strong passwords for you as well.Īnother useful tool is 'xkcdpass', which uses the XKCD method, which is a very different method to create a password. APG does precisely what its name implies: it automatically generates passwords. How do we have our computers help generate strong passwords automatically? This section will cover the Automatic Password Generator application (APG) which is available in Ubuntu via the repository Universe. Now that we've establish what constitutes a strong password. Make sure there is enough entropy, usually counted in bits!ĭiceware is a popular choice (using physical dice + wordlist), but any method that follows the XKCD pattern - pick multiple “words” at random from some dictionary - is good. If your method to choose a password doesn't include a source of randomness (with a computer, or rolling a dice if you like it old-school), it's no good. A password is a compromise between ease of memorizing and ease of cracking, and special characters make password significantly harder to memorize but not significantly harder to crack. Having special characters in a password does not make it stronger. There is no such thing as the strength of a password, there is only the strength of a password generation process. It's a myth that's spread by a lot of websites, but it's still a myth. The idea of “password strength” is a myth. "There is only the strength of a password generation process" Should contain three (3) of the following character types.
This guide is for anyone with sufficient experience with the GNU/Linux command-line, including installing packages using apt-get, and executing command-line tools who also has an interest in passwords, and generating strong passwords with a command-line utility. Such principles are beyond the scope of this guide, and the reader is requested to see the resources presented at the end of this guide for further information on passwords, and formal password policies. This guide does not recommend a formal password policy, including rotation/change scheduling, re-use prevention strategies, and the like. This guide demonstrates the generation of strong passwords with applications available to Ubuntu. If the password you choose is based on common information such as a dictionary word, an attacker may use a so-called "dictionary attack" method of determining your password, and subsequently compromise the account, or data protected with that password. Choosing a strong password for any application, or service which may require one is extremely important. Passwords are the most commonly used security tactic in computing, and are frequently used to protect sensitive information, such as your e-mail account, or your Ubuntu user account. Many security mechanisms present in Ubuntu and elsewhere require a password.
