Question Answer
What is Two-Factor Authentication?

Two-Factor Authentication (2FA) is a security process in which the user provides two means of identification from separate categories of credentials; one is typically a physical code (generated by the Authy app or by Google Authenticator), and the other is something memorised, such as a password. 

The intention is to provide stronger protection against unauthorised access to user accounts.

2FA is used by many organisations to add an additional layer of security to sensitive IT applications and VPN access. Over 75% of the top 25 universities worldwide use 2FA.  

Will I need to use Two-Factor Authentication?

Access to some of the University’s services currently require Two-Factor Authentication to log in, and it is likely others will follow as the need for increased security arises.

Any new services that need 2FA will be communicated to those people who will be affected by any change.

How does it work? Both the Authy app and Google Authenticator generate a short numeric one-time code (often referred to as OTPs) used in addition to your username and password to log into restricted applications. 
What do I need to do if I have to use Two-Factor Authentication?

If you use a service that is protected by 2FA you will need to download Authy or Google Authenticator if you haven't already. Download the authenticator to your smart phone, tablet and/or your computer.
