Duo is the two-factor authentication system that protects your University of Leeds account from unauthorised access. It offers different methods of adding extra security to your account, but we recommend using the free Duo Mobile app, which is available from both the Apple and Android app stores.
Two-factor authentication, also known as 2FA, adds a second method of identity verification to secure your University of Leeds account and the devices, files and systems associated with it.
It’s commonly used for online services, like banking, and works by combining something you know, your password, with something you have, like your mobile phone.
This ensures that even if someone has your password, they still won’t have enough information to access your account.
Passwords are increasingly easy to compromise. They are often stolen, guessed or hacked - you might not even know if someone is accessing your account.
Duo provides an additional layer of security to keep your account secure, even if your password is compromised.
Many University services are protected by Duo, including:
Duo will prompt you to enrol the first time you log in to a protected service. Simply, follow the instructions on screen to register your smartphone, tablet or other device and install the free Duo Mobile app.
The Duo Mobile app is available from both the Apple and Android app stores and is the easiest and fasted way to securely log in to your account.
For step-by-step set up instructions, see our guide to enrolling for Duo.
We recommend that you set up Duo on more than one device in case your primary device is lost or stolen. See our guide or the Duo website for help adding multiple devices.

If you've registered another device with Duo, you can use it instead by selecting it from the drop-down box at the top of the authentication window.
If you haven't registered another device with Duo, contact the IT Service Desk as soon as possible.
You are always required to use Duo to protect your account and the University’s IT infrastructure, unless you’ve been granted a specific exemption.
You need to use Duo to access protected University services wherever you are.
Duo will continue to work as normal over Wi-Fi or mobile data. If you don't have Wi-Fi or mobile data, you can still generate a passcode within the Duo Mobile app by clicking 'Show'. See our guide for more information on using passcodes.
Using the Duo Mobile app in China - If you're travelling to China, we recommend that you download the app before you leave the UK. If you're in China, you can download the app directly from the Duo website. While in China, you may find that you need to use passcodes as your authentication method, rather than receiving push notifications. See our guide for more information on using passcodes.
