Two-Factor Authentication (2FA) for M365

In order to enhance the protection of your accounts and safeguard sensitive information, we will be introducing Two-Factor Authentication (2FA) for all M365 logins

What is Two-Factor Authentication (2FA)?

Two-Factor Authentication is a security measure that requires users to provide two different forms of identification before accessing an account. In addition to your regular username and password, you will be prompted to provide a second factor, such as a verification code or a push notification to your mobile device, to complete the login process.


Why are we implementing 2FA?

Cybersecurity threats are becoming increasingly sophisticated, and it is crucial for us to stay ahead in protecting our digital assets. By implementing 2FA, we can significantly reduce the risk of unauthorized access to your accounts, ensuring the confidentiality and integrity of your personal and academic information.

When will it be effective?

For Staff login, it will be effective on 25 September 2023.

For Student login, it will be effective on 26 September 2023
