Duo is Randolph Macon College’s multi-factor authentication service. It provides an additional level of security to prevent unauthorized access to a variety of systems. Multi-factor authentication helps protect against increasingly sophisticated security threats, like phishing, and thwarts unauthorized use of your login credentials.
HOW IT WORKS
- Sign-in with your RMC email address and password as usual when accessing college resources protected by Duo.
- Confirm your login with an enrolled device when prompted.
- If you did not initiate the push, deny access.
ENROLLING IN DUO
Before you can use RMC services that require Duo authentication, you need to enroll.
Before you start the enrollment process install the Duo Mobile App (iOS or Android) on your mobile phone or tablet. Enable push notifications once the app is installed following Duo’s iOS or Android instructions.
If your phone is not compatible with the Duo mobile app, please choose mobile device and enter your cell phone number with area code. For device type choose Other and then Automatically call this device from the pull-down menu.
To start the Duo enrollment process, open a browser on your computer that you are not currently logged into or an incognito window and sign into RMC Webmail using your RMC email address and password. Duo will prompt you to start the setup process. During the enrollment process you can register multiple authentication methods. Methods supported include: Mobile App with Duo Push, tablet, landline, or security key.
We recommend you register at least two devices during the enrollment process, such as your mobile phone and your office phone/landline as a backup. We recommend registering a mobile phone with Duo Push as your preferred authentication method. To add, reactivate, or remove a device, please see visit Duo’s Guide.
Unified Prompt
Duo now provides a simplified and accessible Duo login experience that offers a redesigned visual interface with security and usability enhancements.
Here is an example of the Universal Prompt:

For users who do not want to receive the DUO push, they will need to select “other options”:

DUO Verified Push Upgrade
Rather than texting a code to your phone for you to enter on your computer, Duo will show the code on your computer for you to enter into your phone when you accept the Duo alert. The requirement to enter a number into the phone ensures that you cannot approve a Duo alert unless you are the person who is logging in on the computer.
The login flow now looks like this:
1. Log in with your RMC username and password
2. Duo displays a code on your computer screen.

3. The Duo app on your phone asks you to enter the code that is on your computer screen. You will enter the 3-digit code into your phone’s Duo app and then tap Verify.

The first time you use the verified push version of Duo on a computer, you will be asked if you are using your own device or a device that belongs to someone else. If you are on your own device/computer, meaning that no one else can use it, select #1 in the screenshot below to remember your device to make future logins faster. If you are on a device belonging to someone else (a classroom or lab computer, for example) please select #2 in the screenshot below to make certain Duo will prompt anyone trying to sign in as you.

Traveling or in a location without cellular or internet access? If Duo Push or calls are not accessible, use a six-digit code generated by the Duo Mobile app to authenticate. Launch the Duo Mobile app on your device to get the authentication code, choose “Other options” followed by “Duo Mobile passcode” in the Duo prompt, put in the passcode, and select login to continue as usual.
