Overview

WebAuthn/U2F tokens are physical hardware devices which can be used to complete multifactor authentication and usually connect to your computer via a USB port but some use Bluetooth. Common WebAuthn/U2F tokens include those from Yubikey, Fetian, and Google Titan.

NOTE: Duo no longer supports U2F but they can usually be added as WebAuthn devices.

This article covers how to add a WebAuthn/U2F token to your Duo account from a Windows computer.
