or

a Second password may be needed.  For the Second password enter: push.  Go to Duo app on your phone/ tablet to Approve.

If push does not work, open the Duo Mobile app on your smart phone - click the refresh icon to the right of the code that comes up to generate a new code and this is your second password (no spaces).

or the Second password is the code showing on your hardware token (see below for additional information on hardware tokens)

Changing your Duo Settings and Devices - including adding a new or additional device

NOTE:  If you need to replace your old device and you do not have access to it, you will need to submit a Support Request to have helpdesk remove your old device from the server.  Please include your RIN for identity verification.
