2-Factor authentication for SSH access
I use the 2FA for accessing the QNAP's web interface and I really love it. However, the current 2FA implementation only covers and protects the web interface but not the SSH access - which is bad for me as I need to have (remote) SSH access enabled for my machine.
Suggestion: enhance existing 2FA and support it also for ssh access. Example: http://www.howtogeek.com/121650/how-to-secure-ssh-with-google-authenticators-two-factor-authentication/
