Cross-Platform: Using PERL

There's a PERL password generator that works for Windows, *nix, OS X, etc.

Usage: genpass [-OPTIONS] LENGTH
-s, --symbols       Exclude symbol characters.
-n, --numbers       Exclude number characters.
-u, --uppercase     Exclude uppercase characters.
-l, --lowercase     Exclude lowercase characters.

On Windows, it can be converted into an executable.


Not specifically what you want, but could also come in useful. In the command line, type:

net user administrator /random    

enter image description here


See answers of this question: Random password generator: many, in columns, on command line, in Linux

Take a look at SecurePassword Kit command line password generator. It has the follwing syntax:

gspk.exe /g [-l:password_length] [-a:charset_options]
