Setting Up Duo Two-Factor Authentication at Northwestern: A Comprehensive Guide
Two-Factor Authentication (2FA), powered by Duo Security, is an essential layer of protection for your Northwestern NetID. It ensures that even if someone manages to get your password, they can't access your accounts without also having access to your registered device. This guide will walk you through the entire setup process, step by step.
Step 1: Initiating Your Duo Enrollment – The Starting Point
Alright, let's begin! The very first thing you'll need to do is access the Duo enrollment portal.
1.1 Accessing the Enrollment Page: Open your preferred web browser (Chrome, Firefox, Edge, Safari – whatever you use!) and navigate to a Northwestern system that requires Duo MFA. Common examples include CAESAR (for students), myHR (for faculty/staff), or NUValidate (

1.3 Welcome to Duo!: After successfully logging in, you should see a welcoming message from Duo Security, likely stating "Welcome to Duo Security." This is your cue to proceed! Click the "Get started" button to continue.
Step 2: Choosing Your Authentication Device – What Will You Use?
Now comes the part where you tell Duo what device you'll be using for your second factor. The most common and highly recommended option is your smartphone with the Duo Mobile app, but there are other choices too.
2.1 Selecting Your Device Type: Duo will present you with a list of device types you can set up. Here's a breakdown of your options:
Smartphone (Recommended): This is by far the most flexible and secure option. You'll use the free Duo Mobile app on your iPhone or Android device to receive push notifications for quick, one-tap approvals.
Tablet: Similar to a smartphone, you can install the Duo Mobile app on your tablet for authentication.
Landline: If you don't have a smartphone or prefer not to use it, you can register a landline phone to receive authentication calls. You'll answer the call and press a button to approve the login.
Security Key (e.g., YubiKey): For advanced users or specific use cases, you can set up a hardware security key. Northwestern might provide these for certain roles, or you can use your own.
2.2 Proceeding with Your Choice: Select the device type that best suits you and click "Continue".
Step 3: Setting Up Your Primary Device (Most Commonly, Your Smartphone)
This is where the magic happens for smartphone users! If you chose another device type, the prompts will be slightly different but generally follow a similar logic of verification. We'll focus on the smartphone setup here.
3.1 Entering Your Phone Number: If you selected "Smartphone," you'll be asked to enter your mobile phone number, including the area code. Make sure it's the number for the phone you intend to use for Duo.
3.2 Confirming Your Number: Double-check that the number is correct and then check the box to confirm. Click "Continue."
3.3 Selecting Your Phone Type: Choose whether your phone is an iPhone or Android device. Click "Continue."
3.4 Installing the Duo Mobile App: You'll be instructed to download the "Duo Mobile" app from your device's app store (Apple App Store for iPhones, Google Play Store for Androids).
Important Tip: Do this before proceeding with the next step on your computer.
3.5 "I Have Duo Mobile Installed": Once the app is downloaded and installed on your phone, return to your computer and click the "I have Duo Mobile installed" button.
3.6 Activating the App with a QR Code: This is a crucial step!
On your computer screen, a QR code will appear.
Open the Duo Mobile app on your smartphone.
Tap "Get Started" or the "+" icon (depending on if it's your first account or an additional one).
Select "Use a QR code".
Your phone's camera will activate. Point your phone's camera at the QR code on your computer screen. The Duo Mobile app will automatically scan it.
Grant camera permissions if prompted.
Once scanned, the app will show "Northwestern University" or a similar name for the account. You can usually give the account a name if you wish, then tap "Done" or "Save."
3.7 Testing Your Login: Duo will often prompt you to approve a test login to ensure everything is working correctly.
On your phone, you should receive a Duo Push notification. Tap to open it and then select "Approve."
On your computer, you should see a confirmation that your Duo Mobile app has been successfully added. Click "Continue."
Step 4: Adding Additional Devices (Highly Recommended!)
You've got your primary device set up – fantastic! But what if you lose your phone, it runs out of battery, or you simply don't have it with you? This is where having multiple registered devices becomes a lifesaver.
4.1 Accessing Device Management: After your initial setup, you'll usually be taken to a "My Settings & Devices" or "Manage Devices" portal. If not, you can typically access it by going to a Duo-protected Northwestern login page, entering your NetID and password, and then choosing "Other options" or "Manage devices" when the Duo prompt appears. You'll then need to authenticate with one of your already registered devices to gain access to this portal.
4.2 Adding a New Device: Click the "Add another device" or similar option.
4.3 Repeating the Setup Process: You'll then be guided through the same device selection and setup process as in Step 2 and 3 for your new device. This could be:
Another smartphone/tablet (e.g., your personal phone if you set up your work phone first, or vice-versa).
A landline phone.
A security key.
4.4 Why this is important: Having a backup device prevents you from being locked out of your accounts if your primary device is unavailable. Don't skip this step if possible!
Step 5: Configuring Default Settings and Understanding Options
Once your devices are registered, you can fine-tune your Duo experience.
5.1 Setting a Default Device: In your "My Settings & Devices" portal, you can select a default device. This means that when you log in to a Duo-protected service, the authentication request will automatically go to this device.
5.2 Choosing Your Default Action: You can also configure what happens when you log in:
Automatically send this device a Duo Push: This is the most convenient for smartphone users. You'll get a push notification right away.
Ask me to choose an authentication method: This gives you the option to select between Duo Push, a passcode, or a call each time you log in.
5.3 "Remember Me" for X Days: When logging in to a Duo-protected service, you might see an option like "Remember me for 7 days" or similar. If you check this box, you won't be prompted for Duo authentication again on that specific browser and device for the specified period, unless you clear your browser's cookies, log off, reboot, or change networks. This is convenient for trusted personal devices.
Step 6: Testing Your Duo Setup
The best way to confirm everything is working is to test it out!
6.1 Try Logging In: Log out of any Northwestern system you're currently in. Then, try logging back into a Duo-protected service (like your Northwestern email, CAESAR, or myHR).
6.2 Verify Authentication: You should now be prompted by Duo.
If you set up Duo Push, you'll get a notification on your phone. Approve it.
If you chose another method, follow the prompts (e.g., answer the call, enter the passcode).
6.3 Success!: If you successfully log in, congratulations! Your Duo Two-Factor Authentication is set up and protecting your Northwestern accounts.
