Choosing your 2-factor device

Mobile phone:

This option supports both smartphones and basic mobile phones. You will be able to verify your identity by receiving a phone call, a passcode via text message or, for smartphone users - a simple push notification.

Where possible, using your smartphone is the most seamless option. As part of the setup process you will be guided to download the Duo Mobile app onto your phone or tablet. This will then enable the push notification to be sent to you when logging in, from which you will simply tap ‘Accept’ on your phone to authenticate.


This option allows you to use your tablet to receive push notifications or a passcode (via the Duo Mobile app) in order to complete the authentication process.


The landline option is only recommended if your phone is located in a secure area. When you answer the phone call, you will be given instructions to follow.

Duo key fob:

If the mobile, tablet or landline options don't work for you (eg if you work in a lab where phones are not allowed) you can collect a Duo key fob from the IT Support Centre in the Kilburn Building. This can then be used to generate a six digit code to enter into an on-screen prompt to authenticate.
