What is Duo? Duo two-factor authentication adds a second layer of security to your accounts. Verifying your identity using a second factor, like your smartphone or other mobile device, hardware token or entering a security code, prevents anyone but you from logging in, even if they know your password. You'll login as usual with your username and password, and then use your device to verify that it's you. Commonly asked questions about Duo two-factor authentication are listed below.
Q: What services are protected with Duo?
A: All applications that offer SSO (single sign-on), like Office 365, Dropbox, Moodle, Zoom, Slate, Maxient, and Google Docs require Duo two-factor authentication. Additionally, VPN access from off-campus and confidential applications like Banner and Blackbaud require Duo.
A: There are several methods to authenticate in Duo:
- Duo Mobile Push
If you use your smartphone or tablet, you can install the Duo Mobile app and send a notification to your device. To authenticate, you choose to Accept or Deny the request on your mobile device.
- Duo Mobile Passcode
If you use your smartphone or tablet, you can install the Duo Mobile app and generate a temporary passcode from that app. This works even if you don’t have access to wifi or cell phone service.
- Using a provided Duo token
If you cannot or will not use your mobile device to authenticate, the T&I Support Center can provide you with a Duo token. You will press a button on the token to generate a passcode that you can then enter in the portal.
- Using a personal hardware token/fob
If you have a hardware token already (ex: Yubikey), you can insert the token, like a USB, and tap it to authenticate. T&I can also provide you with a Duo token which will generate a temporary passcode.
Do I need a smartphone to use Duo? What if I don’t have a smartphone?
A: If you have a smartphone, you’ll find it makes Duo more convenient.
- You probably already have your smartphone with you, and it’s easy and quick to acknowledge a login through the Duo app.
- You can choose to use the Duo app for two-factor protection on personal services like Gmail, Instagram, Facebook, and other sites.
- If you do not own a compatible smartphone, T&I will provide one Duo key fob (for students) or one authentication key (faculty/staff) at no cost.
Q: I already log in to services frequently. Will this slow down my work or studies?
A: We hear you, and we’re working to make login faster and more efficient.
- T&I is moving our most widely used services (including email, Dropbox, Moodle, Google Suite, Zoom and more) to a common login experience, so you won’t be prompted to log in as often. More services, like Banner Self-Service, will join this login experience over the course of the year.
- With the roll-out of Duo for everyone, you’ll be able to opt for Duo to “remember me” when you sign in. This will reduce the number of Duo prompts you receive on that device.
- We are working to improve the ease of accessing services in other ways. For instance, we are evaluating ways to make a number of IT services available from off-campus without VPN later this academic year, once all of our community uses Duo.
