After successfully enrolling in **Duo two-factor authentication**, you can manage your Duo settings through the **Duo 2FA app in PirateNet**. The Duo Self-Service app allows you to perform the following tasks without contacting the Technology Service Desk:

- Add a new device or phone number
- Remove an existing device or phone number
- Update an existing device or phone number
- Re-register the Duo Mobile app on a device
- Change settings for an existing device or phone number

These steps apply to users who have a new phone or who have deleted the Duo Mobile app and need to re-activate Duo Mobile on the same or a different device.
