Overview

Learn how to register a second (or more) device for your two-step login process. The interface will walk you through the process. You can register mobile devices and tablets for use with two-step login.

Critical Concepts

---

• In order to make changes to your two-step login setup, you'll first need to use an existing, registered device to verify your identity.
  
  • If you do not have access to your primary device, contact the ITS Service Desk.
  • If you have not yet registered for Duo, check out the instructions on how to do so on our article: Register for Two-Step (DUO)

• It is recommended to register multiple devices in case one device isn't available for any reason. Losing your only device will mean you will need to contact the ITS Service Desk directly for assistance.  

• The callback option for Duo has been removed. More information can be found on Retirement of the Duo Callback Option. 

Steps to Take

Select the type of device you are registering for device specific instructions:

• Smartphone
• Cellphone (non-smartphone)
• Tablet
• Hardware Token

Smartphone

These instructions will help you install and enable the Duo Mobile App on your smartphone so that you can start authenticating Duo Push. Duo Push will allow you to easily tap a notification you receive on your phone to log in. 

1. Visit the two-step login device management link (https://duo.ucsd.edu) and use Active Directory to login. This will need to be done on your computer. 
2. Use an existing, registered device to verify your identity through the two-step process.
3. Click Add another device. 
4. Select the Mobile phone option, then click Continue.
5. Enter the cell phone's number.  Verify the phone number is correct and click the checkbox to confirm. Click Continue to proceed.
6. Choose the type of phone you are registering, and click Continue.
7. You will be prompted to install the Duo mobile app (if you haven't already).
8. Follow the instructions on screen to install the Duo Mobile app on your phone. You will be looking for the green Duo Mobile app, pictured below.
   
   
   
   
9. Once you have installed, open the app and you will most likely want to allow Duo to send notifications to your device.  This will lead to the most seamless experience using the two-step login.  Otherwise, each time you log in you'll have to open the app to approve.
10. Back on the registration screen, click I have Duo Mobile installed.
11. Follow the instructions to open your Duo app and scan the barcode that appears on screen (you may need to grant Duo Mobile permission to access your camera).  This is the key that ties your identity to your device! 
12. Once activated, click Continue and you should be taken to the "My Settings & Devices" page where you should be able to see your newly added phone.  

Cell Phone (Non-Smartphone)

If you do not have a smartphone or do not want to install the Duo Mobile App on your smartphone, you can register a cell phone to receive text messages for two-step login:

1. Visit the two-step login device management link (https://duo.ucsd.edu) and use Active Directory to login. This will need to be done on your computer. 
2. Use an existing, registered device to verify your identity through the two-step process.
3. Click Add another device. 
4. Select Mobile phone and click Continue.
5. Enter the cell phone's number.  Verify the phone number is correct and click the checkbox to confirm. Click Continue to proceed.
6. For the phone type, select Other (and cell phones) and click Continue.
7. Once the device has been added, you should be taken to the "My Settings & Devices" page where you should be able to see your newly added phone.  Here you can add additional devices or change your default two-step login settings. 

Tablet

Tablets, such as iPads and Android tablets, can be used for the two-step login via the Duo Mobile app.  If you have a smartphone that does not have a phone number, you can also register the device following these steps.

1. Visit the two-step login device management link (https://duo.ucsd.edu) and use Active Directory to login. This will need to be done on your computer. 
2. Use an existing, registered device to verify your identity through the two-step process.
3. Click Add another device. 
4. Select Tablet and click Continue.
5. Select whether you are using an iOS or Android tablet and click Continue
6. You will then need to install the Duo Mobile App on your tablet using your tablet's app store (ex. App Store for iOS or the Google Play Store) 
   
   
   
   
7. Once you have installed the app, click on I have Duo Mobile installed
8. Follow the instructions on screen to link your tablet to Duo.
9. You should then be taken to the "My Settings & Devices" page where you should see your new tablet added.

Hardware Token

Tokens are a small hardware device that generates passcodes on demand to use with the two-step login. Tokens may be useful to staff or faculty who are unable to use a phone during work or those who don't have an office or cell phone available. Hardware tokens are available for pick up at the ITS Service Desk and the Hive or can be sent to your campus mailbox via the campus mail services.

Please keep two things in mind regarding tokens:

• A passcode can also be generated from within the Duo phone or tablet app. The app-generated passcode is accessible even without a cell or wifi connection. Whether you're on a flight or a ship, traveling internationally or working in a subterranean bunker, if you're using the app and have the device, you should be covered. 
• It is best practice to register multiple two-step login devices. Even with a token, you'll want a backup plan for the day you lose it or leave it at home. Therefore, we recommend setting up various devices to complete two-step login to ensure you have multiple options. 

How to Request a Token:

1. Make sure you've already registered for Duo. If you haven't registered for Duo, you can refer to our article: Register for Two-Step Login (Duo). 
2. Request a token using the Duo Hardware Token Request Form.
