How do I register a security key for Duo?

This article guides you through registering a security key for Duo multi-factor authentication (MFA) at Colorado State University. A security key is a USB device that must be connected to your computer for use with Duo. Two types of deices may be used as security keys:

A USB fob, available for purchase at your campus bookstore.
Your smartphone, allowing you to authenticate using your smartphone without installing the Duo Mobile app.

Security keys cannot be used with remote devices (e.g., RDP, SSH, websites visited on a VM). Hardware tokens are available for purchase at your campus bookstore or technology store for those who need remote access but do not wish to use Duo Mobile.

Prerequisites

You will need access to a previously established Duo authentication method (e.g., Duo Push or passcode).

Instructions

Navigate to https://netid.colostate.edu/ and log in with your NetID and password.
When the Duo prompt appears, select Other options.
From the options menu, navigate to the bottom and select Manage Devices.
To proceed, authenticate using a previously established method or a bypass code from the CSU IT Help Desk.
Once authenticated, select Add a device from the Manage Devices menu.
In the add device menu, select the Security key option.
At the set-up security key menu, click Continue. This will open a popup in your browser with the message "duosecurity.com wants to see the make and model of your security key".
You have two options for adding a security key:
- Plug in a USB security key and touch it to activate it (recommended).
- Use your smartphone to scan the provided QR code to add your smartphone as the security key.
