 Adding a Phone to Duo

 Instructions for adding a phone to the duo two-factor authentication service at the University of Cincinnati.

When using Duo, you may need to add a new phone to your account for any of the following reasons:

  You get a new phone with a different phone number.
  You want to have additional devices to use as back-ups (for example, you use your cell phone but want to have office phone available just in case).
  You want to add the Duo Mobile app to a phone previously registered as a generic cell phone.      
  You got a phone with a different operating system than you previously had:
      o   You used to have an iPhone, but now have a Windows phone or an Android.
      o   You used to have an Android, but now have a Windows phone or an iPhone.
      o   You used to have a Windows phone, but now you have an iPhone or an Android.
  You have another device already associated with Duo, but you would like to have additional sign-in options.
Note: If you got a new phone, but kept the same phone number, and none of the other conditions above apply, you may want to see Reactivate Duo Mobile instead.

 

To add a new phone:

1.  Go to https://webapps2.uc.edu/getduo, click Enroll/Manage Duo, and Sign in.
     Note: If you are already signed in, you will need to sign out before completing this step.
2.  On the left of the sign-in page, select 
Add a new device.
3.  Choose an authentication method (Send Me a Push, Call Me, or Enter a Passcode), and finish signing in.
    *Note: If the reason you are adding a new phone is to activate Duo Mobile on a different phone, you will need to choose either Call Me or Enter a 
     Passcode (because Send Me a Push requires Duo Mobile).
    **Note: If you cannot sign in to Duo (e.g. if the only device registered was a phone you no longer have and the phone number has changed), please
       contact the Integrated Service Desk at 513-556–HELP (4357).
4.  Select the type of device you are adding, then push Continue.
     *Note: Since you are adding a phone, you will choose either Mobile Phone or Landline.
     **Note: Office phones are considered Landlines.
5.  Enter your phone number.
6.  Check the box that says This is the correct phone number.
7.  Push Continue.
8.  At this point, the instructions change depending on what type of phone you added:

        Note: Scanning the QR code will not work if:

  You are using your phone to sign up for Duo, rather than a computer, tablet, or other second device (You cannot use your phone to scan a
