7.1 Logon using SSH keys on CD

A very secure way to logon to a Linux system is to use SSH public and private keys that are on a CD. You can mount the CD at login time, access your keys, type in your passphrase, then remove the CD. This way, even if someone is able to grab your password or passphrase, they still don't have your keys because they are on the CD.
