This article is a step-by-step guide to using two passwords with EncFS. The primary password is required and may be used to secure all data; the secondary password is optional and may be stored on USB stick or other removable media and used to secure more sensitive data. EncFS can also be combined with block device encryption for maximum security. Block device encryption is described in a previous article by Michael Petullo, Disk encryption in Fedora: Past, present, and future.
