This option on the classroom sign-in page allows you to quickly set up many computers or devices. When you tell XtraMath to remember your network, our server temporarily remembers your IP address. This means you don’t need to enter your password on each new computer or device, as long as they are on the same network.
This authorization lasts for two hours. You can terminate it sooner by clicking Forget my network on the classroom sign-in page. It does not allow anyone to sign in to your teacher account or view student scores, but it does reveal your name, and the names of students in your classes, to other computers on your network.
