This document describes the best practices for MFA-Duo Authentication when cellular/internet services are unavailable.
You have several options for MFA-Duo that will work both within the US and internationally.
If you change your SIM Card
To generate a passcode:
- Simply open the Duo Mobile app and click the UW Madison NetID Login down arrow located at the upper right-hand corner of your smartphone. This will generate a six-digit temporary passcode.
- Enter the six-digit code provided on your smartphone in the Multi-Factor Authentication portal to complete the authentication process.
Smartphone or tablet with the Duo app installed
- When you have a wifi or cellular signal, you can still "push" a notification to the app.
- When cellular or wifi signal is unavailable, you can use the Duo Mobile app to generate a passcode. For more on this, see: MFA-Duo - Obtaining a Passcode from the Duo Mobile App
Token/Fob or security key
- If you do not have access to a smartphone or tablet, you can use a token/fob. For more on this, see MFA-Duo - How to use a token/fob
Generate 10 Backup Codes for Future Use
- Each backup passcode can only be used once, so we recommend crossing them off as you use them.
- Backup passcode will expire after four months. The expiration date is displayed on the print out below the passcodes
- Generating new backup passcodes will invalidate your previous backup passcodes, even if you haven't used all of them.
- For more on this, see MFA-Duo - Generating Backup Passcodes for Future Use
If you don't have access to a smartphone, tablet, or token/fob or security key you can call the DoIT Help Desk at (608) 264-HELP and an agent can assist you by generating a temporary passcode.
