Note on acronyms

Below we describe in detail how to work with 2FA. It is quite straight forward once you get the hang of it.

Before you can use 2FA we and you need to setup a few things.

• You should own a Smart Phone or own/obtain a YubiKey from the IT department: Since during the 2FA process you need to generate passcodes (a six digit number) automatically based on a secret key, or enable push authentication you and the 2FA system have exchanged, you need a device to perform this action. This device can either be an app on a Smart Phone or a YubiKey hardware device. If you don not own a Smart Phine or cannot use that for any reason, contact the Physics IT Helpdesk to obtain a Yubikey.

First time access:

• Enroll in Duo to setup Multi Factor Authentication

Web sites that require 2FA use the DUO enrolled information to provide normal access to the Web site after you have provided your 2FA credentials.

VPN allows your home desktop or laptop to become part of the Physics Computer network. This will be the new way to connect to local Physics services (Tunnelier will be discontinued).

• Convert previously configured VPN to use 2FA
• Remote Desktop access via VPN (and 2FA)

Using ssh in a 2FA environment

It might happen that you loose your smart phone or yubikey, or otherwise may be deprived of your secret key. In that case you need to perform the following actions to reset 2FA in the given order:
