Using Multi-factor Authentication (Duo Mobile) with poor cell phone or Internet service

If you have an Android or iPhone with Duo Mobile installed, you have several ways to login to Northwestern systems that require multi-factor authentication: with a touch notification ("Duo App"), a phone call ("Call Me"), or a text notification ("Text Me"). In situations where you do not have good cell phone reception or Internet access, you have an additional method to be able to login to multi-factor-authenticated systems using the "Enter Passcode from Duo" method, by following the instructions below. This method has the added benefit of being completely free since it does not use your Cellular data package.

  1. Open Duo Mobile on your phone, tap the key icon, and note the six-digit number:

  2. In the Duo Mobile app, the key icon is to the right of the Northwestern University logo, and underneath the plus sign
  3. Go to the web address of the system you are trying to access and log in with your NetID and NetID password
  4. When prompted to confirm your identity, select Enter Passcode from Duo

  5. Under the notification method, the 4th radio button for 'Enter my passcode now' is selected
  6. Enter the six-digit code from Duo Mobile and your identity will be confirmed
