NetIDplus is UTD’s implementation of Duo two-factor authentication. Just as your cash is safer when an ATM card must be combined with a pin code, NetIDplus combines your NetID account with your mobile phone or code-generating device to protect high risk systems.

For help enrolling in Duo, any questions regarding using Duo to authenticate into our Duo-Protected applications, or for help managing your Duo devices, please refer to the documentation below.

Authenticating with a Security Key

The next time you log on using Duo, you can simply tap or insert your security key to log in. Some types of keys flash as a prompt for you to authenticate. You do not need to explicitly select the security key from the drop-down list of available devices to use it for authentication in Chrome if you also enrolled it in Chrome.

In other browsers, you may need to select your security key from the drop-down list of your authentication devices. Once you select your security key from the list, click Use Security Key and tap your security key when prompted.

Existing U2F Users: Security Key Update

If you’re a user who enrolled a U2F token for Duo authentication before the security key update, you’ll be prompted to update your security key registration for that device the next time you log in with Chrome using that U2F authenticator.

Simply click Continue and tap the security key.

Once the security key registration is updated via Chrome, you can use that security key in both Chrome and Firefox.

What are Security Keys?

A security key plugs into your USB port and when tapped or when the button is pressed it sends a signed response back to Duo to validate your login. Duo uses the U2F and WebAuthn authentication standards to interact with your security keys. You may also see WebAuthn referred to as “FIDO2”.

Security Key Requirements

In order to use a security key with Duo, make sure you have the following:

  • A supported browser (Chrome 70 or later, Firefox 60 or later, or Opera 40 or later).
  • An available USB port.
  • A supported security key. WebAuthn/FIDO2 security keys from Yubico or Feitian are good options. U2F-only security keys (like the Yubikey NEO-n) can’t be used with Firefox.
