Common Issues

Most people will use a smartphone to authenticate with Duo. If you are having issues, the solution may depend on whether or not you had the Duo app installed and connected to their OU account.

  • New phone number– contact us at 325-HELP (4357) or by visiting needhelp.ou.edu
  • New phone, same number – there should be no changes necessary

If you receive a new phone and a new phone number, you must contact us regardless of whether you had the Duo app installed/connected to their OU account or not.
If you have a smartphone with an incompatible (likely international) phone number, you will need to set up Duo differently.

  • Select “Tablet”, rather than smartphone, during setup.
  • Choose the operating system: iOS or Android.
  • You will be instructed to install Duo Mobile for whichever operating system you choose.
  • Once you have Duo Mobile installed on the device, select “I have Duo Mobile installed”.
  • You will be given a barcode to scan to activate Duo Mobile, or you can request an activation link to be emailed to yourself.
