Duo Hardware Token Authentication

Overview

If you have received a hardware token from the Information Security Office, you can also use it to log in.

1. Navigate to a Duo protected site (Office.com or Galaxy) and log in using your UTD credentials.
2. Enter the passcode in the space provided and click Verify. 

Troubleshooting

If your Duo hardware token has stopped working, please follow the steps below to "re-sync" the token with the Duo servers.

1. Navigate to a Duo protected site (Office.com or Galaxy) and log in using your UTD credentials.
2. When prompted by Duo, enter three consecutive and correct passcodes from your hardware token, in three successive authentication attempts within 5 minutes.
   • The first two authentications will fail.
3. However, the passcodes will resynchronize and the third authentication should succeed.
