actually Bruce Byfield explains it in Linux Magazine:
Pass is available in the repositories of most major distributions. As usual, you can also compile from scratch, but, if you do, take note of the dependencies, especially GnuPG (GPG) [6], which creates encryption keys, and Password Generator (pwgen) [7], which generates random passwords that contain random combinations of upper- and lowercase letters, numbers, and special characters. Without GnuPG and pwgen, you will be unable to set up Pass, much less actually use it.
