After several rumors, WhatsApp is finally rolling out the option for its users to use two-factor authentication under their account settings folder. According to Android Police, the feature is already available on the the most recent early versions of the app (2.16.341 and above), and it is also been spotted in the Windows Phones beta.
Two factor authentication allows users secure their accounts better, once activated, the app will prompt a user for a static six-digit passcode every time a new phone is registered to the account.
Two-factor authentication will defend your WhatsApp account against hackers
This kind of authentication has always been seen an a burden and some kind of inconvenience, but it provides a crucial line of defense against criminals who might try to hack your phone. Currently, the only way of to register your WhatsApp account without two-factor protections, on a new device is a confirmation SMS message — but since that message is sent to all devices registered under your phone number, it’s a recipe for disaster for things to go wrong if the hacker has cloned your device.
The feature is currently still only in beta versions of the app, but will roll out in the official release very soon.
