In today's ever increasing threat environment, a password simply isn't enough by itself, and it is alarmingly easy for attackers to steal one form of authentication, but it is much more difficult to steal multiple forms. Therefore, from the 14th of February 2024, MFA Everywhere will be enabled, which will mean that MFA will be required on and off campus; while working from home, travelling, or working on campus, you must complete MFA authentication when using Office 365 or accessing other online MU services.
Update on 14-Mar-2024:
MFA Everywhere and the move to the more secure Microsoft Authenticator App - these changes are on the way! The original deadline of the 14th of February 2024 was extended to allow users more time to update their provision and also for additional user support options to be available. The new deadline is confirmed as the 18th of April 2024. Further details will follow on additional supports to enable this change.
