A new security feature called number matching will be introduced to the Microsoft Authenticator app. If you use this app for your multi-factor authentication (MFA) you will notice this change from 22 February. When you log in with your Single Sign-On (SSO) you will see a number on the SSO screen which needs to be typed into the app to complete the approval process for your MFA. Full details of this change, including instructions of what to do, are available on the IT Services website. This added security applied by Microsoft will help to keep student and staff data safe. Other authentication methods are unaffected. General information about MFA can be found on the IT Help website.
