RandPass is a program designed to create random passwords in various customizable formats: lowercase letters only, uppercase letters only, numbers only, or a combination of all of them, including eliminating similar characters or adding specific symbols.
You can also choose the number of characters that you want your password to be, and the number of keys that you want RandPass to generate. Once you've established those parameters, the tool will display different passwords with different lengths and complexities, so you can choose which ones you want according to your needs.
Thanks to this program, no one will ever be able to access your social network accounts, or any other web service or page that contains your private information. Of course, if you don't have a good memory, you'll probably want to note your passwords down somewhere so you don't forget them.
