To prevent unauthorized users from gaining access to an account with a stolen password, DUO 2FA is introduced to provide a second-layer security to protect an user account. When using DUO 2FA, an additional piece of information, i.e. a Duo Push Response / One-time Passcode, is required during login to Microsoft 365 and VPN connection.

• Student Accounts: 3 Nov 2020
