Multi-factor authentication (MFA) is a security mechanism that requires you to provide two or more pieces of evidence to authenticate your identity. For example, logging in to a website at home may also require you to approve the access via an app on your mobile phone or to enter a code sent to it. This provides an additional layer of security to ensure your account is not compromised.

MFA and Microsoft 365

Access to Microsoft 365 outside of the University of Otago network requires a second form of identification using a mobile device. An authenticator app should be downloaded to your mobile phone, or if this is not possible, an authentication code can be sent to you via SMS.

You will need to set up MFA when you first log in to Microsoft 365. After setting it up, make sure your mobile phone is available nearby when you sign in to Microsoft 365 in case you need to reconfirm your identity.

Once MFA is set up on your mobile phone, your ongoing access to Microsoft 365 will be linked to it. If you lose or replace your phone, you will need to contact AskOtago to have that device unlinked from your account.
