YubiKeys are small USB dongles that you can plug into your computer. They can simulate keyboard input, allowing you to enter One Time Passwords (OTPs) with the press of a button to authenticate with services. YubiKeys can also be used when logging into a remote server. This video will show you how to configure your Linode server so that a YubiKey must be plugged in and tapped in order to log in to your server using ssh.
