Are you searching for the guide to configure the 2-step authentication? You are at right place.  Here is the guide that will help you to configure the linkedin two-step verification .

Before getting into the actual steps, let me explain what 2-step auth is.

Two-Step Verification:
A security feature that prompts you to enter a temporary secret number sent to your phone whenever you log into your account.

Why you should enable this feature?
I believe this is best security feature.  Let us assume, someone has stolen your login credentials via keylogger or phishing or any other method.  If the hacker try to log into the website with your credentials, he will asked to provide the secret number sent to your mobile.  Fortunately, you have your mobile with you ;) .  So hacker can't log in to your account.  Also you will come to know that someone is trying to access your account.
