What is Keylogger?

A keylogger is a software program that copies or records the keystrokes that a user inputs through a keyboard to a mobile device, computer, or related system. Keyloggers are typically employed with the intent of stealing sensitive information such as passwords, pin numbers, or other confidential data — often with the intent of financial gain, or to steal personal information needed to hack into a website, bank account, crypto wallet, computer network, or hardware or software system.
