Overview
Duo hardware tokens (Duo branded, or Feitian C100) may drift out of sync with Duo servers. This article covers how to resync an out of sync token.
Step 1
From a Duo universal prompt, select "Other Options".

Step 2
Select "Hardware token".

Step 3
Enter your the passcode from your token and select "Verify".

The login attempt will fail. Repeat Step 3 twice more. The second attempt will also fail. After the third attempt, proceed to Step 4.

Step 4
After the third attempt, you should get a "success" message. Your token has been resynced successfully.

If you do not get a success message after the third attempt, contact your TSP, Local Support, or the STC for assistance at support@uidaho.edu.
