MFA-Duo - Best Practices for Using Duo

This document will highlight the best practices for using MFA Duo.

1. Register more than 1 device or generate backup codes for future use

If you've ever been in a situation where you don't have your MFA device with you, you know this can be a major inconvenience. Give yourself some options ahead of time so you don't get into a bind:

Generate backup codes for future use

Note: You will need to be able to authenticate with Duo in order to reach the page to generate backup passcodes. If you currently cannot sign into Duo, try generating a temporary passcode (see MFA-Duo - Request a Temporary Passcode).

Generating Backup Passcodes for Future Use

  1. Navigate to the Multi-Factor Authentication Portal at www.mfa.wisc.edu. Authenticate with your UW-Madison NetID and Password. You will also be asked to approve the login through your existing multi-factor authentication devices.
  2. Click the blue Create Backup Passcodes button.
  3. MFA portal section for generating backup passcodes

  4. Click the blue Print Backup Passcodes button.
  5. Green message indicating that the passcodes have been created, with a button labeled Print Backup Passcodes

  6. Click Print to print your passcodes or write them down if you do not have access to a printer
  7. Print dialogue with the backup passcodes displayed as a document


Handling Your Backup Codes

  • Backup codes should be stored in a secure but accessible location (such as a locked drawer or cabinet) while not in use.
  • Generating new backup codes will invalidate your previous backup codes.
  • Backup codes will expire after four months; The expiration date is displayed on the print-out below the passcodes.
  • Each code can only be used once so we recommend crossing them off as you use them.

2. Use the "Remember Me for 12 Hours" option

Having to use MFA Duo for every NetID login session can become tedious. Use the "Remember Me for 12 Hours" option to minimize the number of times you'll need to authenticate with MFA Duo:

Use Remember Me for 12 Hours

Note: The "Remember me for 12 hours" function is not currently working with Safari version 13.0.3 on Mac OS 10.14.6 (Mojave). Duo is aware of the issue, and it should be resolved soon.

Note: Some users have reported issues using "Remember me for 12 hours" on iOS version 14.2 across all browsers.

Please see the Troubleshooting section below if you find that "remember me" is not working for you.

In order to login with Duo Multi-factor Authentication, you must have first set up a device and linked it with your NetID. If you have not yet completed this, follow the instructions here: MFA-Duo - How to Enroll for MFA Duo for your NetID Login Account

Using "Remember Me for 12 hours"

  1. Navigate to a page that requires Duo Multi-factor Authentication after NetID login (e.g. MyUW).

  2. Authenticate with your NetID and Password.

  3. After authenticating with Duo, you will be prompted with the following dialogue box:

    Is this your device?

  4. Selecting Yes, this is my device will remember your browser session for 12 hours. Be sure to select No, other people use this device if you are on a shared computer.
    1. When the remembered device cookie expires, the Duo two-factor authentication prompt for that application shows Remember me checkbox (shown below) as an enabled option on the Duo Push, phone call, text message, and passcode authentication screens. Users can uncheck the box before completing Duo authentication to log in without remembering the browser on this device, or leave it enabled to set a new remembered device cookie for the application.

               Remember me checkbox

  Troubleshooting "Remember Me"

Users may find that they are prompted for MFA-Duo within 12 hours even after they have selected the "remember me for 12 hours" box. The "remember me" feature relies on a browser cookie to function.
"remember me" may not work in the following situations:
  • If you close your browser or switch to a new browser.
  • If you switch to a different computer.
  • If you are using private/incognito browsing mode.
  • If your browser does not allow cookies to be saved.
  • If you clear your browser cookies
Here are some basic troubleshooting tips to ensure that "remember me" works.
  1. Make sure that your internet browser allows cookies from the duosecurity.com domain to be stored in your browser.
  • In Safari, go to Safari > Preferences > Privacy. Under Cookies and website data click Allow from websites I visit. Restart your browser and try "remember me" again.
  • In Internet Explorer, go to Tools > Options > Privacy. Adjust the slider for the Internet zone to allow third-party cookies to be stored. Restart your browser and try "remember me" again.
  • In Firefox, go to Firefox > Preferences > Privacy & Security. Ensure Third-Party Cookies are not blocked. Under Cookies and Site Data click Accept cookies and site data.
    Restart your browser and try "remember me" again.
  • In Chrome, go to Preferences > Settings > Show advanced settings > Content settings. Ensure Block third-party cookies is not selected. Restart your browser and try "remember me" again.
  • If you have browser extensions or plug-ins installed, disable or remove them to see if "remember me" works. Many browser extensions and plug-ins prevent cookies.
  • If the steps above do not resolve the issue, please contact the DoIT Help Desk.
