Contents Introduction Target Audience “Strong Passwords” or “Strength of a password generation process” Strong passwords “There is only the strength of a password generation process” So how should I choose passwords? 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. Choosing a strong password for any application, or service which may require one is extremely important. 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. This guide demonstrates the generation of strong passwords with applications available to Ubuntu. 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.

A dictionary word however long has a password space of around , i. Another way of selecting a password is to have “symbols” common words and select only 4 of those symbols. Using such symbols was again visited in one of the tips in Security Advice.
It is absolutely true that people make passwords hard to remember because they think they are “safer”, and it is certainly true that length, all other things being equal, tends to make for very strong passwords and this can be confirmed by using rumkin. Even if the individual characters are all limited to [a-z], the exponent implied in “we added another lowercase character, so multiply by 26 again” tends to dominate the results. In addition to being easier to remember, long strings of lowercase characters are also easier to type on smartphones and soft keyboards.
For any attack we must assume that the attacker knows our password generation algorithm, but not the exact password. In this case the attacker knows the words, and knows that we selected 4 words, but not which words.

Article updated to reflect the latest Best Practices: 23 July Passwords are still a mainstay of securing web application authentication systems. They can also be the source of many usability issues and productivity issues. Passwords are ubiquitous and have been used to authenticate trusted users into systems even before the internet. Password policies that enforce high entropy passwords and best practice rules on passwords have the best chance to prevent unauthorised access into a system.
The most common password-related threats to authentication security are:. Authentication processes need to be easy to remember and understand, but also need to be usable and not take too long to complete. Having a single authentication scheme a password manager for example to gain access to all sites, aids the convenience of only having to remember a single process, pin, and password.
However, this also introduces a single point of failure. For example, if someone were to gain unauthorised access to this system, then the same individual would also be able to gain access to all other listed services as well. Authentication systems, in general, can be too complex and time consuming for the average user, especially those working in a time-sensitive environment such as healthcare, security and defence.

The breach is alleged to have been the result of a flaw in the open-source phpBB message board software.

The records appear to mostly be hashed using the bCrypt algorithm, although some accounts are still encrypted via the older, less secure md5 encryption method. It has been suggested that these are old, unused accounts which pre-date the forum’s shift to bCrypt encryption.
