Generate completely random, hard-to-memorize passwords.

This prevents someone from being able to “shoulder surf” the user’s chosen password. Used interactively, pwgen will display a screenful of passwords, allowing the user to pick a single password, and then quickly erase the screen. Hence, its default behavior differs depending on whether the standard output is a tty device or a pipe to another program. The pwgen program is designed to be used both interactively, and in shell scripts. On the other hand, completely randomly generated passwords have a tendency to be written down, and are subject to being compromised in that fashion. Without the -s option should not be used in places where the password could be attacked via an off-line brute-force attack. In particular, passwords generated by pwgen Human-memorable passwords are never going to be as secure as completely completely random passwords. The pwgen program generates passwords which are designed to be easily memorized by humans, while being as secure as possible. Update: I have since moved to Homebrew since Mac Ports did not upgrade in time for one of the macOS updates. I use Mac Ports only because it was the one I ran since I moved to macOS over 6 years ago. On macOS, you will need either Homebrew or Mac Ports. To run this in Linux, you can use your package installer of choice: apt-get install pwgen I ran the selected password through multiple password strength testing sites and although I got different responses, the password is generally safe with my normal 60 day password reset policy. In my example, I am saying to run ‘pwgen’ without ambiguous letters (not to be comnfused with other letters like ‘0’ (zero) and ‘O’ (the letter)), include symbols, include numbers, include capital letters, and use the option for ‘hard to guess’ password. I can choose any of them or even multiple ones and concatonate them. In this example, I am creating a bunch of random password based on 23 characters.Īs you can see in the results, I have created random passwords. Depending on the size and complexity I need for my password, you can modify it via the command line. I used to use this back in my Linux days. When I need to generate a random password, I use an opensource package named pwgen.
