WhatsApp is a must have application nowadays for every smartphone user. There had been some issues in the past regarding privacy.

Now WhatsApp is giving us the option to add extra security.  There is only a two step verification method for this.  We can see it during the messages that all the messages are encrypted. This makes all data private and secure and and there is one extra step when you log in the WhatsApp. You will get the passcode when you sign in and the passcode is a six digit code.

Do not forget the passcode otherwise WhatsApp will lock you for seven days.

Now follow me step by step. I have also attached the screen shots.
