Do I have to use Duo every time I log in?

In general, no - you will have the option to “trust” the computer you are logging in from for 30 days. (This option requires you use the same browser and not clear your browser cache). Keep in mind the option to “trust” the computer is application specific. For some applications, like HR Direct, you can trust the computer for 30 days. Other applications (like VPN) may not have that option available.

There are several common reasons why you may not be able to select the option to remember your device.

  • If you have configured Duo to automatically send you a push, text, or call instead of asking you which one to use
  • If you are connecting via an iPad, iPhone, or Android device
  • If your web browser does not have cookie support enabled. Make sure that cookies are enabled in Internet Explorer (if you're using Windows) or Safari (if you're using a Mac), or Chrome.
