Duo: Two-Step Not Working for "Remember Me"

Problem

  • Duo two-step "remember me" feature is not working on your web browser.  You may be receiving an error message when you try to select "Remember me for 7 days" or may be receiving the two-step login prompt repeatedly, despite selecting this option.

Cause

The "Remember me" feature for Duo two-step login relies upon your web browser's saved cookies. If you have already selected the "Remember me for 7 days" option on you web browser, but still keep getting prompted to perform two-step verification each time, this usually indicates that your web browser is blocking third-party cookies such as Duo Security.

Cookies are small files that save basic data that allows your browser to remember your preferences or activity on a website - Duo uses cookies to track when you have selected the remember me option.  This means that "remember me" only remembers your specific web browser, not your computer, so if you are switching over to a different web browser or device, the remember me option will not carry over.

Resolution

If the "remember me" feature is not working, follow these steps to add an exception to allow third-party cookies from Duo Security:

Chrome
  1. Open Chrome and select More (three vertical dots) in the top-right, then select Settings.
  2. On the left hand side, select Privacy and security.
  3. Locate the "Privacy and security" section and select Third-party cookies.
  4. Next to Allow, select Add.
  5. Enter the following: [*.]duosecurity.com
  6. Click Add.
  7. You may need to restart your browser for changes to take effect.
Firefox
  1. Open Firefox and select Menu (three horizontal lines) in the top-right, then select Settings.

  5. Select Allow, then Save Changes.
  6. You may need to restart your browser for changes to take effect.
Safari

Safari does not have an option to add individual exceptions for sites.  You will need to enable third-party cookies on Safari to allow Duo Security to remember your two-step login:

  1. Select the Safari drop-down menu from the top menu bar.
  2. Select Preferences...
  3. Click Privacy tab.
  4. Make sure that "Block all cookies" is unchecked or set to Never.
  5. You may need to restart your browser for changes to take effect.
  6. Safari 13.1 and later: You must also disable the Prevent cross-site tracking option.

If your browser is not listed, please consult your web browser's support pages for allowing third-party cookies.
