Download of APG 2.2 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The application lies within Security Tools, more precisely Personal Security. This free Mac app is an intellectual property of 13cubed. Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe.
From the developer:
APG generates passwords with two (2) to eight (8) random common dictionary words. It displays length and approximate bits of entropy. The length of the password is often more important than the complexity.
