I use and advocate secure authentication, verification, and encryption methods. Naturally, I have used 2-Factor-Authentication for a long time wherever it is available (Google, Facebook, Dropbox, and many others). In addition, my computers and mobile devices use Full Disk Encryption, protecting my data at rest.
The YubiKey is a small USB device that augments different authentication methods to accomplish these tasks. I recently purchased two of YubiCo’s latest model, the YubiKey 4 to help me with 2FA and FDE.
