When you're prompted to verify your identity using Duo Mobile, you are given four (4) methods by which you can do so: Send Duo Push, Duo Mobile passcode, Send text message passcode, and Call phone.
By default, Duo Mobile will send a Push notification to its assigned device. Once confirmed, you may opt to remember your authentication in this browser on this device/computer by checking the Remember me for 30 days checkbox.
For more information on this feature, see How "Remember me" works in Duo multi-factor authentication.
If you do not have Duo Mobile Push configured, or you would like to select a different option, click Other options to view the other available methods of authentication.
Duo Push
This is the recommended method for verifying your identity. All it requires an active Internet connection.
Open Duo Mobile on your device (or tap the notification banner, if enabled) and tap Approve to log in.
Enter Duo passcode
Click Use Duo Mobile passcode to open a text field.
Open Duo Mobile on your registered device and tap the downwards-pointing toggle arrow to reveal a passcode. To generate a new passcode, tap the circular arrows.
Enter the passcode into the field shown below and click Verify.
Send text passcode
Click Send text message passcode to open a text field.
You will receive a text (SMS) message from (313) 214-2215 with the passcode enclosed. You may save this number as Duo Passcode in your Contacts for your convenience.
Call Phone
Click Call Phone to send a phone call to your registered phone.
Answer the call and follow the automated voice prompt to approve and log in. It will ask you to press any key on the dialpad.
You may save the phone number (847) 467-9000 as Duo Phone Call in your Contacts for your convenience.
If you are unable to authenticate using any of these methods (i.e., you lost your phone, you don't have any devices to register with Duo, ...etc.), or for additional assistance, please contact the IT Support Center at 847-491-4357 (1-HELP) or via email at consultant@northwestern.edu.
