If you use an iOS device (iPhone or iPad) and Apple Mail and Calendar It offers the familiar features of Outlook email and calendar but can be accessed through a web browser on your computer, smartphone, or tablet. If you cannot upgrade Office 365 and Outlook, consider using Outlook on the web to access your Cornell email. Upgrade if you can, then enroll in Two-Step Login and authenticate with Two-Step Login whenever you are required to login. On Windows and macOS, you will need to have Office 2016 or later to be compatible with Two-Step Login. (But you are still being protected against any malicious users who try to access your account from a different computer or smartphone.) If you use Office 2013 or older As you may already know, as long as you use the same device and app to access your email regularly, Office rarely requires a new login, unless you use a different device or haven’t logged in for a long time. You will need to enroll in Two-Step Login and authenticate with Two-Step Login whenever you are required to login.

How often you need to log in varies depending on your settings, but you can reduce the number of times you need to log in by clicking Yes when you see the Stay Signed In prompt during Microsoft Office sign in. If you don't already have a Two-Step Login account, go to Get Started with Two-Step Login to begin the process. If you are subject to mandated use of Two-Step Login with CUWebLogin, that requirement will not extend to Office 365. Two-Step Login for Office 365 is completely independent of opting in to expanded use of Two-Step Login with all services that use CUWebLogin. Don't worry, Two-Step Login is still giving you its extra protection against malicious users. With Outlook on the web, you will be prompted to complete Two-Step Login only if you usually need to sign in there. One time you might would be when you install a fresh copy of the software. You will rarely, if ever, need to authenticate with Two-Step Login when you use an app on your computer or mobile device to access Office 365. After Two-Step Login has been enabled, if criminals manage to steal your NetID password, they will be unable to hijack your email account or access sensitive content stored in it. It is part of the university’s comprehensive strategy and aims to improve data security for email, calendars, contacts, and other shared Office resources. Whether Two-Step Login has been mandated for your Office 365 account or you are choosing to opt in, it protects access to your email, calendar, and all other Office 365 services.
