These instructions assume that you are already using Two-Step Verification and would like to add additional phones or tablets. If you've never used Two-Step and are being prompted to complete the setup for the first time when you try to log into a Brown service, see this article instead: Set Up Two-Step Verification If Auto-Enrollment Occurs.

You can repeat this process for each of your phone numbers or devices.

Part 1: Using a Smartphone or Tablet? Install the Duo app.

If you're enrolling a landline, or an older cell phone like a flip phone, skip to the next part. 

1. If you are enrolling a smartphone (recommended if you have one), install the Duo Mobile App on the phone using the appropriate link: iPhone/iPad | Android | Windows Phone 

Out of room on your phone? Don't want to install an app? You can continue the setup anyway (skip step 5 in the next section, too). You will miss out on the ultra-convenient push notifications and offline features provided by the app, but you can still receive a phone call or text.

Part 2: Add Your Device or Phone Number

1. Go to https://myaccount.brown.edu/twostep/settings and log in
   

   (if typing the address instead of clicking the link, make sure to include the "s" in httpS)

2. Click the Add link appropriate to the device you are adding (for example, "Add Smart Phone" or "Add Landline").
   

3. Provide information about your phone or device. For example, if I were to add an iPhone, I might fill out the form like this. The Device Name field is just for your reference. I chose the name "My iPhone" to make it easier for me to identify the phone in the future.
   International number? Add a + in front of your country code (for example, a German number would start +49).
   
   
   

4.  If you added a new landline or "non-smart" cell phone, you are done!
   If you entered a shared phone number that is already registered by someone else, you will need to receive a text or phone call at that number to prove that it is your number. Read the text on the screen for guidance.
   
   If you added a smartphone or tablet, you need to complete a final step described here. You will see a QR code (black and white square) after submitting the form.
   
   

5. On your smartphone / tablet, open the Duo Mobile app you installed in Part 1. Click the Add Account button or the plus icon on the top right of the app (on the Android it is a key with a plus sign).
   
   Allow notifications and camera if prompted. Hold your smartphone / tablet up to the computer screen to scan the QR code - it will happen almost instantly. 

6. 

Now your phone is paired with your Brown account! You can repeat to add more phone numbers or devices.
