Keylogger

A malicious program or device that records everything you type into a device, including passwords and other personal details, allowing others to secretly collect that information. (The "key" in keylogger refers to the keys you have on your keyboard.) Keyloggers are often malware that users have been tricked into downloading and running, or occasionally physical hardware secretly plugged into a keyboard or device.
