Duo - Resync Fob - Incorrect Passcode. Please Try Again.

This article will help you resync your FOB should it fall out-of-sync.

If you receive the below message, your FOB may have become out-of-sync.


Incorrect Passcode


Select the Correct Device (if applicable)

If there is a Device field above of the box you enter your passcode, make sure it says Token. If this field is not listed then Token is your only method to sign in and it is already selected (even though you do not see it).

Device - Token


How to Resync Your Fob

Note: If at any time you click Log in and the passcode does not match what is on the FOB or if you click Log in more then once for a passcode you will have to start the syncing process over.

  • When your Fob has a blank screen, press the green button one time. Enter the number from your FOB in the Passcode box then click Log in. You should receive the "Incorrect passcode. Please try again." message.  
  • As soon as your Fob has a blank screen again, press the green button one time. Enter the number from your FOB in the Passcode box then click Log in. You should receive the "Incorrect passcode. Please try again." message.  
  • As soon as your Fob has a blank screen again, press the green button one time. Enter the number from your FOB in the Passcode box then click Log in. You should now be logged in.

How to Prevent a Duo FOB from Becoming Out-of-sync
  • Do not let passcodes on your FOB go unused. 
    • Store your FOB in a place that the button will not get constantly and accidentally bumped.  
      • This may include not storing your FOB in your pocket or in any other places that may cause the button to be pressed. 
    • Do not purposefully press the button and then not use the passcodes. 
    • FOBs that are not used for a very long period of time may fall out-of-sync. 



If you are unable to get your FOB to resync on your own or your FOB regularly falls out-of-sync or you have locked yourself out of your Duo account after too many authentication attempts, then please contact the Eagle Help Desk at x8774 for assistance.
