MFA-Duo - How can I use the "Remember Me" function?

This document will provide instructions for setting the "remember me for 12 hours" feature. The "remember me" feature makes MFA-Duo more convenient by reducing the number of times that you'll be prompted for MFA-Duo on the same device using the same browser. The "remember me" feature remembers your current browser 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.

  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 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.
