Hardware tokens generate a one-time passcode for Duo authentication. They can be used without a cell signal or WiFi connection.

## Get a Token

Submit a [Duo Hardware Token Request](https://calpoly.atlassian.net/servicedesk/customer/portal/2/group/12/create/46). Once your request is approved, your token can be picked up at the [Service Desk](https://calpoly.atlassian.net/wiki/spaces/CPKB/pages/909246477). 

## Use a Token

Authenticate with a Duo hardware token and a passcode.

1. Log in to the [My Cal Poly](https://myportal.calpoly.edu/) portal or Cal Poly MFA/Duo-enabled application.
2. Click the **Enter a Passcode** button.
3. Press the button on your Duo hardware token to generate a new passcode.
4. Enter the Passcode in the field and click the **Verify **button.
  
5. Once your identity is verified, your Cal Poly account will be authenticated.

> ℹ️ If you see an “Incorrect passcode. Please try again.” message, your hardware token may be out of sync. To re-sync it, generate and enter a passcode three times. On the third time, you should successfully log in.
