 === Setting Up Two-Factor Authentication ===
-Due to recent brute force ssh attacks we are moving to using two factor authentication (2FA). Existing users will have one week to switch over to this process.  New users are expected to do this within 24 hours.  This is pretty easy to setup as follows (from a terminal in your mac or linux laptop (and Windows if new enough)) or using PuTTY. All commands to be run are will be in <code>code</code> block. If you have not already established a connection with jumpgate (from the previous steps above), open a new terminal and enter the following:

 Next you need to download and install an authenticator application either for your computer or phone. There are several from Google, Microsoft, Twilio, etc (Google Authenticator works great). Launch that application on your phone or computer. In whatever mode it uses to create a new token generator, do that (often it opens with a QR code scanner enabled as it knows that is the easiest way to link the phone application to the QR scan created on the machine you are trying to access).
-Before moving forward, it is recommended that you start a second terminal connection to <code>jumpgate</code> by repeating the process above for establishing an ssh connection (PuTTY steps for Windows 8 users). We will refer to this second terminal connection as our "backup terminal". If at any point you want/need to reset, simply run <code>''rm -rf ~/.google_authenticator''</code> in the backup terminal.

 The entry point for the group machines is <code>jumpgate</code>, which is accessed publicly via <code>jumpgate-phasta.colorado.edu</code>. We access this entry point by creating an SSH connection between it and our personal machines.
