Duo Security Devices

Multi-factor authentication (MFA) adds an additional layer of security on your accounts by requiring two forms of verification before granting access to an account. CTS uses Duo Security tools to manage the second form of verification. Once you are enrolled in Duo, you will use a second device in addition to your password to sign in to MFA-enabled services. For a complete list of MFA-enabled services, visit duq.edu/authentication.

Devices you already own, such as a mobile phone or Apple Watch, can be enrolled in Duo for MFA logins. In addition, there is no limit to the number of devices you can enroll in Duo. CTS recommends registering at least two different devices in case you do not have access to one of your devices. For instance, you can enroll your mobile phone as well as your office landline phone in Duo. If you would leave your mobile phone at home, you could still log in to MFA-enabled services using your office landline phone.

Action Items

Step 1: Decide which MFA devices best suit your needs

The table below describes each of the MFA devices you can use for logging in to MFA-enabled services. CTS recommends enrolling devices you currently own in Duo.

Step 2: Enroll a device you own in Duo

Devices such as mobile phones, tablets and Apple Watches can be enrolled in Duo. Most individuals own some or all of these devices and carry them with them throughout the day. CTS recommends enrolling at least one of these devices in Duo. This helps ensure you always have at least one device on you at all times that can be used to complete an MFA login.
