With Two-Factor authentication, each time you login from a new device, you will be required to enter your password and then a secondary confirmation via your cell phone or an app on your smart phone.
Below are the instructions for setting up two-factor authentication - you must start by setting up your cell phone for two-factor. (You will need to be in an area with good cell reception! Some areas in the school may have limited cell coverage).
Please follow this article to first set up your phone to receive text messages and then install/set up the smart phone app called Google Authenticator (setting up your cell phone is a pre-req for Authenticator app). The benefit of Google Authenticator is that it will work even when there is NO cell coverage!
