The Facebook-owned messaging app service WhatsApp is rolling out an extra layer of security that will help you keep all your WhatsApp conversation private.
It has introduced two-factor authentication (2FA) in some of the latest beta version of the WhatsApp, according to Android Police, a blog that reviews Android products.
The 2FA is available in the version 2.16.341 and above, maybe even earlier, it said.
Two Factor Authentication is a multi-factor authentication that requires not only a password but also another peace of information that only the user knows.
An user needs to get it activated via their account by clicking on two-step verification menu and need to fill the six digit pass code that they had created. This passcode they need every time they use a new phone and want to use same WhatsApp account.
With the two-factor authentication your conversation to remain private and no one other than you can activate the WhatsApp account using your phone number unless they have the passcode.
