mkpass is a simple command line utility to generate secure random passwords. You can easily redirect these to a clipboard or copy and paste as needed. I use a password manager and generate random passwords every time I need one. And while most password managers include a generator, there are times I need one outside of that. The code is written in java so it should run on any OS that supports it. Lastly, the idea and core code came from a Wikipedia article. I just took this and expanded upon it. https://en.wikipedia.org/wiki/Random_password_generator This is a single executable JAR file. While you will need Java installed, there is no need to install this program. Just download the JAR file, please it somewhere convenient, and execute it from the command line: java -jar mkpass.jar See home page for additional details and usage instructions. https://github.com/frossm/mkpass
