Duo Help Video from ITS
In the video below, UT’s Information Technology Services (ITS) introduces Duo, a multi-factor authentication service. Duo is used as an extra layer of security to make logins more secure.
To learn more about Duo and how to use it, you can view the videos below. Closed captioning is available via the [CC] button.
What is Multi-Factor Authentication (MFA)?
Authentication is the process by which a system determines that you are who you claim to be.
There are multiple factors of authentication, which can be broken down into categories:
- Something you know, such as a password.
- Something you have, such as your mobile phone.
- Something you are (i.e., biometrics), such as your fingerprint.
When you use more factors of authentication, the system can be more confident that you are who you claim to be, leading to better security.
For example, your password might be compromised when a website gets hacked, but with multi-factor authentication, that password is useless without your mobile phone.
Why am I Being Asked to Complete MFA?
To better protect the security of your online information, the university has implemented MFA using the Duo product. When you log into any university web application protected by MFA, this system will come up.
Before you can complete the authentication process, you will need to enroll a device. The recommended device is a smartphone or tablet, such as an iPhone or Android device.
If you have not enrolled a device, please follow the instructions below. You will need your chosen device handy to complete this process.

| Security Key |
Authenticate with a touch of a button (no passcode needed). The generic term is "security key," and one example is the YubiKey, a product made by YubiCo. Security keys configured for the university's MFA service can be purchased at the Campus Computer Store.
Security keys sold by the Campus Computer Store are configured for the university's MFA service and are incompatible with the YubiCloud OTP validation infrastructure. |
| Duo Mobile Generated Passcodes | Enter a passcode generated with the Duo Mobile application or generated by your hardware token. Click 'Enter a Passcode' to make use of this functionality. |
| Hardware Token |
Authenticate with a one-time passcode generated from a portable hardware token. The generic term is "hard token" or "token".
Hardware Tokens configured for the university's MFA service can be purchased at the Campus Computer Store under product ID#1867833 |
| Touch ID |
In order to use Apple Touch ID, make sure you have the following:
A MacBook Pro or MacBook Air with a Touch ID button.

Registering Backup Devices
The university strongly recommends that you register more than one device.
- In the event that your primary device is lost/stolen/broken, you can use your backup device to remove the lost/stolen/broken device and add a new one.
- In the event that your smartphone or tablet is reset to factory settings, you can use your backup device to remove and re-add that smartphone or tablet.
- If you do not configure a backup device, you will need to contact the UT Service Desk if your only device becomes lost, stolen, broken, or reset.
- For directions to add a backup device, please visit: Device Management
