Virginia Tech uses Duo Security to ask individuals for a secondary confirmation of their identity at log-in, using a physical device in their possession. The device may be a smartphone or tablet using an app, a text message to a phone, or an automated voice call to landline or cell phones.

How do I enroll?

When you log in as usual (with your ID and password) to access services using the new procedure, you will be prompted to enroll.

To enroll: Select the devices you plan to use from the menu. Registering two or more devices is recommended. Because they can receive information in multiple ways, one of these devices should be a phone. Enter your device information. If you are enrolling a smartphone or tablet, you will be asked to install an app from your appropriate app store.

Follow the simple instructions for each method to complete the process.

Change your devices

You may add or remove devices from your profile by selecting “Manage devices.” on the Duo system screen, and following the prompts.
