I use Vim as my main password manager instead of the popular 1Password. I even wrote an article about it. Anyway. The only thing that I miss is a password generator. This is why I created this very simple online password generator.
I use the awesome Jen library to generate random passwords. On a sidenote, I'm the worst JS developer the world has ever known - so if you want to change the code and enhance it, it wil be very much appreciated.
The site is hosted on Divshot. It's great and free for a personal project. To push the code to production, simply divshot push production and it's done. Woot. Now I can go back on building other stuff.
