Two-step login means that when you  log into a protected system (step 1), you be prompted to approve this login from your default device (step 2).

For systems that are not using SSO

For systems using SSO (Google mail, Zoom, TMS..) and you have a Duo account:

1. Enter your NetID and NetID password. 

2. A screen will appear letting you know what device will send a push or call. 

3. Approve the login on your default device.

Be sure you have at least 2 devices enrolled in Duo.
