Duo Multi-Factor Authentication Setup

What is Two-Factor Authentication?
Two-factor authentication adds a second layer of security to your online accounts. Verifying your identity using a second factor (like your phone or other mobile device) prevents anyone but you from logging in, even if they know your password.

How It Works
Once you’ve enrolled in Duo you’re ready to go: You’ll login as usual with your username and password, and then use your device to verify that it’s you.

You can use your mobile phone, landline, tablet, or USB security device. Duo lets you link multiple devices to your account, so you can use your mobile phone and a landline, a landline and an iPad, two different mobile devices, etc. You can receive your verification code via SMS, voice call, one-time passcode, the Duo Mobile smartphone app, and so on.

Using Duo MFA

Step 1: Download and Install Duo Mobile

Please Note – fake versions of the Duo Mobile app have been reported. The legitimate version of the app is called “Duo Mobile” and is published by “Duo Security, Inc.” It is free to download.

Recommended Practices for Using Duo MFA

  • When possible, use the Duo Push authentication method. Set the Push as the default option in the Duo settings.
  • Adding a second device is highly recommended in the event you are without your primary device.
  • Some smart devices can accept the notification from the lock screen by using force touch.
  • Desktop clients typically require re-authentication less frequently than web applications. When using the web application, you will have the option to choose “Remember me for 8 hours.” After the 8 hours, you will be required to use Duo again when accessing the applications on the web.
  • If Duo keeps prompting for login after authenticating. Try the following:
    • Close the prompt for authentication.
    • Close the application and open it again.
  • If you change your cell phone, but keep the number, use the ‘Call Me’ or ‘Enter a Passcode’ options to reactivate your phone.
  • If you change your cell phone, and change the number, use the second device you registered to authenticate, login and add the new device.
