Microsoft 365 is fully licenced for you while you're a college student. This enables all students to be able to use Office365 online as well as be able to install Office365 onto your own devices. You also have a healthy storage capacity on OneDrive to store your coursework.
Microsoft 365 is accessible both on-campus and off-campus. However, to use off-campus, you will need Authentication setup. This is fairly straight-forward to setup. The first time you try to login off-campus, it will ask you setup authentication and guide you through the steps.
