NOTE: Remember Me should only be used with a device you own or that is assigned only to you. Never use the feature on public or shared devices.
You must enable a ‘cookie’ from Duo to allow this feature to work.
Specific instructions from Duo are HERE
When you check Remember me for 9 hours, your browser is what does the "remembering." This means that Your DUO authentication will not be remembered when you:
- Switch browsers
- Use a private or Incognito window in your browser
- Use a different computer
- Clear your browser's cookies
- Have your browser block third-party cookies
For example, suppose you checked Remember me for 9 hours this morning when you were using Chrome. When logging in after lunch, you decide to use Safari or Firefox. Because you switched browsers, you'll be asked to verify your identity with Duo again.
Finally, if your web browser is set to clear cache and cookies upon close, the Remember Me option will not work. You can disable this in Chrome or Firefox.
