To continue to use Apple Mail, MacOS users will need to upgrade to a supported OS. Apple Mail in MacOS 10.13 and lower does not support two-step authentication. Two-step authentication will help limit the impact of phishing on Stanford's population (most phished accounts are used to send spam and more phishing attacks). This is rolling out gradually across the University and will include all SUNetIDs with e-mail service by October, 2020.
Stanford's email system (Microsoft Office 365) is being upgraded to require two-step authentication. Two changes are driving the need to upgrade: Due to these changes, most Apple computers in H&S will need to be upgraded to MacOS 10.14 Mojave or MacOS 10.15 Catalina.
In the coming months, there will be several changes to Stanford's IT infrastructure that will affect our Apple computer users.
