Password Generator Pro automatically generates passwords, serial numbers, and random numbers. It features 5 methods for generating the passwords: normal generation where you can choose the contents (letters, numbers, and special characters), masked generation where you specify patterns describing the passwords, dictionary mode where it grabs random passwords from a file you specify, pronounceable mode for easy to remember passwords, and character list mode for making passwords consisting of a chosen list of characters. All the functionality is available in command line form, so you can integrate the features in your own system. Can generate up to one billion unique passwords at once, 1000 characters in length. Generation is very fast, even when generating millions of unique passwords.
