      pass is a very simple password store that keeps passwords inside gpg2
      encrypted files inside a simple directory tree residing at
      ~/.password-store. The pass utility provides a series of commands for
      manipulating the password store, allowing the user to add, remove, edit,
      synchronize, generate, and manipulate passwords.
