Where do I find the security code for my wireless network?
If you are using a wireless modem/router, the default password/passphrase/security code is sometimes printed on a small sticker on the back, side, or bottom.
What is a security code on Wi-Fi?
It is commonly called Wifi or wireless network password, and it is used for connecting to WiFi networks. Access points and routers are already configured with a network security key that you can change in their settings pages.
