WhatsApp has finally added two-step verification as an account security option, but it appears to only be available in some of the beta versions of the app presently.
As expected, the feature can be found in the Account menu under Security.
Enabling it will require a 6-digit passcode to be entered before registering your phone number with WhatsApp.
The two-step verification option appears to be available in WhatsApp beta version 2.16.341 and higher, though you may spot it in some other beta versions as well.
You ll need to create a six-digital passcode 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.
