Duo: Remove Remembered Devices

On occasion you may click the "Yes, this is my device"  box (device remembers you for 30 days) on a Duo prompt on a computer that actually should prompt you each time you sign in.  For example, if you work with sensitive college information, and are signing in to check email on a home computer, you may decide you'd prefer that computer always prompt you.  If you have clicked that box, there is a way to remove the specific cookie that Duo sets to remember you.
