The project is built around the Atmel AVR ATmega168 microcontroller and has an LCD display and numeric keypad with alphanumeric entry capability to show and enter information respectively. It plugs in to the computer through a USB interface managed completely by software. In addition, no driver installation is necessary on the host computer, and it works independently from any web browser and operating system, so that it can be used with Windows, MacOS and Linux computers using any web browser, such as Internet Explorer, Netscape, FireFox, etc. This Password Managing System is designed by Carlos Cossio.
