Security & privacy Security and Encryption Encrypted keystrokes for maximum security All new Logitech cordless keyboards now include secure encryption that protects what you type. Logitech is the only company making cordless keyboards that securely encrypt data using a secret key, to protect it even if it is intercepted using professional equipment. You can easily switch the encryption mode on or off, using our keyboard feature control panel.
How does it work?
You can easily switch the encryption mode on or off, using our keyboard feature control panel. During the process, you're asked to enter a given 16-digit key. Secured transmission is then turned on, even if your reboot or turn off your PC. The odd to have a similar key on any other system is similar to finding someone with your exact same DNA code - virtually nihil. We take your privacy seriously, so that you don't have to worry about it. It can easily be switch on or off at any time.
Make any sence where i can turn this off !!!!
