Add Extra Security to macOS Mail and Calendar with Two-Step Login for Office 365
Starting with macOS 10.14 (Mojave), if you use Mail and Calendar to access your university Office 365 email and calendar account, you can take advantage of added security with Two-Step Login for Office 365.
Previously, only the mobile version (iOS 11 and later) of Apple applications worked with Two-Step Login. Now, however, users with Mac desktop and laptop computers who choose to use Apple Mail and Calendar instead of Microsoft Outlook can take advantage of the extra protection that Two-Step Login provides against abuse of their email accounts.
