Protect your account not only with your password.
WhatsApp is now rolling out two-step verification for everyone. This means an additional layer of security, to all of its users on iOS, Android and Windows. It’s an optional feature which you can set up by heading to Settings, followed by Account and Two-step Verification inside the app.
You’ll be asked to create a six-digit passcode, which will then be required every time you try to register your phone number with WhatsApp (for instance, when setting up your account on a new smartphone).
You can also designate an email address which, in an emergency, can be sent a link to disable the feature. WhatsApp highly recommends this as a rescue solution, just in case you forget the code.
Also, to help you remember, WhatsApp says it will ask for your code “periodically.” Disturbing, but it’ll guarantee you more security especially if this is your primary communications app.
