Overview
Duo offers the following methods of authentication:
Duo Push: the most common and recommended way users utilize two-factor authentication. This requires (1) either an Android or an Apple smartphone with the application installed and enrolled to your Active Directory account, and (2) an internet connection.
Duo Passcode: This also requires the Duo Mobile application installed to a smartphone but does not require an internet connection.
SMS Text: This does not require a smartphone; instead, it uses SMS text messaging in the authentication process.
Voice: This is most commonly used in a situation where there is no cell service but a LAN line is available to receive a phone call. This is a less secure option, since anyone can answer the phone. To use this option, you must register your landline's phone number on remote.ucsf.edu.
YubiKey: This is a physical USB key that you plug into a computer to provide secondary authentication. For more detail on this option, see the YubiKey section below.
Bypass code: This is a temporary passcode that you can use as your secondary authentication method. Bypass codes must be requested in advance and only by the person who will use them. They expire after 30 days.

YubiKey
A YubiKey is a USB key that you plug into your computer's USB port to provide secondary authentication. YubiKeys are the keys to all of your accounts, so do not keep them with your computer in case it is ever lost or stolen.
YubiKeys have specific system requirements, so before submitting your request, refer to https://www.yubico.com/support/knowledge-base/categories/downloads/ and make sure your device is supported.
Replacement YubiKeys cost $30 each, so safeguard your YubiKey and file a report immediately if it is lost or stolen.
