humanpwd generates several passwords that consist of four words each. The passwords will only contain lower-case English words without numbers, special symbols, etc. Based on the idea from the popular XKCD comic.
There were already some password generators based on that idea, but most of them are over-engineered and will only give you one password at a time. humanpwd is much simpler and straightforward.
humanpwd is available as a website and as a stand-alone binary.
