As expected, the feature can be found in the Account menu under “Security.” Enabling it will require a 6-digit password to be entered before registering your phone number with WhatsApp. I totally agree with that security and privacy is what we needed.
You’ll need to create a six-digital password that will need to be entered before you can register your phone number with WhatsApp. Users can enter their email as an optional extra layer of security.
By including your email address, says WhatsApp, you can have the service send you a link to terminate the two-step verification, the company’s solution for users who forget their passcode.

But having a security like this is really good. And now not only in Whatsapp,Facebook Messenger and other social media aloow End-to-End encryption chat.
