Multi-Factor Authentication 

Multifactor authentication (MFA) refers to additional authentication by phone when logging in to online services. In addition to the username and password, another authentication method is a code sent to a mobile phone by text message or a separate authentication application.

Multi-factor authentication is required every 90 days, after changing your password and when logging in on new devices.

Services covered by MFA

Multifactor authentication is used in TUAS Microsoft 365 cloud service. Without multi-factor authentication, you cannot log in to TUAS services that use an email address as a username. These include email, Messi and Teams workspaces. Joining Teams meetings doesn't require multi-factor authentication.

Not all mobile phone email applications support multi-factor authentication. We recommend using Outlook application to manage TUAS email and calendar.

1. Log into https://aka.ms/mafasetup. 2. Install Microsoft Authenticator to your phone and select Scan a QR code. 3. Remember to add an alternate authentication method.
