The Facebook owned messaging app WhatsApp introduced two-step verification for beta users back in November, last year and the messaging platform is now rolling out the feature to its all 1.2 billion users. The feature brings an added layer of security to the service, and allows you to secure your account with a six-digit passcode that you choose.
You can set up two-step verification by heading to Settings -> Account -> Two-step verification -> Enable. Once you set up the passcode, WhatsApp will send you periodic reminders to ensure you don’t forget it. You can also optionally add an email address to your account which will be used to reset your passcode if you forget it.
To remind you, WhatsApp rolled out full end-to-end encryption for all communications last year so, every call you make and every message, photo, video, file, and voice message you send, is end-to-end encrypted by default, including group chats.
