[ENCRYPTION] Add security to your Linux devices.

[kiraitachi]

Hi mates I wanted to share this interesting post I found at : http://studyhat.blogspot.com.es/2013...or-fedora.html

I already use 2 step verification for some of my services like dropbox google and other. Although I didt knew that I could implement this services on my own Linux machines.

Here is a how to for Fedora 20. Wich is pretty straight forward. I already done it for my ssh login to my raspberry pi on ARCH.

Im sure for Kubuntu is already a good step to take on.

Use google-authenticator for Fedora Login
Install Google Authenticator for Fedora

If you set up 2-step verification using SMS text message or Voice call and also want to be able to generate codes using the Android, iPhone or a Blackberry, you can use the Google Authenticator app to receive codes even if you don’t have an Internet connection or mobile service.
Prerequisite :-
Android Phone.
Barcode scanner.
Google Authenticator App on Phone.
On Laptop as Follow.
[root@localhost rajat]# yum install google-authenticator -y
Loaded plugins: langpacks, presto, refresh-packagekit
