Hardware Password Manager

A hardware password manager that is plugged in between a keyboard and a computer. In pass-through mode, it does nothing with the keystrokes. In password manager mode, it allows you to type in the login you want to select, and then input a simple password. The password manager hashes the password and inputs it into the computer.
