Turning on this security feature could save your account - and device - from attack.
Graham Cluley explains:
WhatsApp has released a new two-step verification (2SV) feature that allows its 1.2 billion users to verify themselves on a new device.
The maker of the end-to-end encrypted messaging app announced the new feature back in November 2016. At that time, it was available only to members of its beta program. Fortunately, it didn't take long for WhatsApp to open the security measure up to all of its users.
Regular readers now all about what two-step verification entails. It's an expansion of single-factor authentication (SFA) by which someone authenticates themselves using something they know, something they have, or something they are. 2SV adds another step to this authentication process.
