WPA2 Code

You mean for connecting to your wireless internet ? It's usually printed on the back of your internet router.

WPA2 WPA2 stands for: Wireless Protection Access version 2. It is your Wifi passcode.

Wifi routers will sometimes have a sticker on the back side, or underside of them with the default network name and default code printed on it.

If you have not changed it since you got the wifi router, then that should be it. Look on your Wireless router for the sticker.

If you did change it at some point, then only you would know what you changed it to, and no real way to find it unless you wrote it down.
