There are many login options depending on the device you enrolled. You will usually log in through the web and select your login method using Two-Step Login's authentication prompt. You can choose to be notified on a mobile device, called on your phone, or you may enter a passcode. For some campus IT services that don't support a web interface, you may have to log in using append mode authentication or using a second password field.
