===Using with Virginia Tech 2-Factor (Duo)===
There are two ways to use two factor with CAS Shibboleth ''login''. Both will require Chrome (or Chromium may work, but is currently untested). Option 2 allows Firefox usage after the initial setup.
1. Open Chrome. When logging in using CAS, the Duo popup will open asking what source to use for two factor. On the sidebar, click add device. It will want to confirm using an existing method first. Then, select that you want to enroll a U2F token. Follow the instructions onscreen to enroll. Once completed, you can just tap your Yubikey (or other U2F token) to authenticate.
