What Others Think

keepassx will generate passwords, and also store them securely. It is a nice program and worth checking out.

pwgen is another good tool. Allows you customize the type and number of passwords you want to be generated.

I was just wondering, what is the program that has this command for use sitepass. I looked around but couldn't really find it, I'm running Snow Leopard so hopefully I can compile it from scratch. Would be greatly appreciated.

its a function. you create a function / command in bash by using that syntax. e.g. this_is_a_user_defined_command() {echo foo; }
