Duo: Troubleshooting Duo not remembering you for 30 days

If you never see the "this is my device" or "remember me" option

If you use the "Call me" option to receive phone calls from Duo, the "this is my device" or "remember me" option is not possible. We recommend setting up your phone or tablet to receive push notifications, or obtaining a DUO fob if you do not have a device capable of installing the DUO Mobile app.

If you see "this is my device" or "remember me" but it doesn't work

The "remember me" or "this is my device" feature requires that your browser allows cookies.

1. Click the Cancel button or the X button in the blue bar.
2. Check the box next to "remember me for 60 days"
