Multi-factor authentication (MFA) or watch this video from Microsoft:

Staff can change their MFA at any time by following the steps outlined in the related article: ITS Cyber Security recommend that staff use the Microsoft Authenticator mobile application as it provides the strongest security for University of Otago Microsoft 365 accounts and data. If you are unable to install the Microsoft Authenticator app on your mobile phone, you can receive a text code as an alternative method. You will need to download the 'Microsoft Authenticator' app from the Apple or Android app stores to your mobile phone. For example, a login on your web browser at home may also require you to approve access via an app on your mobile phone or to enter a code sent to it. Microsoft 365 uses multi-factor authentication ( MFA) as its security mechanism and this requires you to provide two or more known pieces of information to authenticate your identity. This can be either a work cell phone or a personal cellphone.

For security reasons, staff who want to use Microsoft 365 (formerly known as Office 365) outside of the University network must have access to a mobile phone.
