Our website provided a free download of PassPGen 2.2.4 for Mac. The program lies within Security Tools, more precisely Personal Security. This free Mac app was originally developed by AtalantiaDevelopment.
From the developer:
PassPGen creates as many random pass codes of any length as you like, and stores them as a text file in ASCII or UTF8. You should use this software to prevent your passwords from being hacked by social engineering, brute force or dictionary attack method.
You may want to check out more software for Mac, such as PasswordVault Lite, which might be similar to PassPGen.
