WhatsApp is rolling out two-step verification to all its users on Android, iOS, and Windows after testing the feature since last November. It’s an optional feature meant to boost security of your messaging account—it’s disabled by default, so you must enable it yourself to reap the benefits. When enabled, you’ll be required to input a six-digit code of your choice when you’re asked to verify your phone number.
Enabling two-step verification is easy: just navigate to the Account page under Settings in WhatsApp and choose Two-Step Verification. After you make your six-digital authentication code, you’ll be asked for it every seven days as well as whenever you need to verify your phone number (for example, when you register your account on a new phone). You can also add an e-mail when you enable two-step verification which WhatsApp will use to e-mail you a link to disable the feature if you ever forget your code.
But let’s say you forget your code but didn’t enter a recovery e0mail in WhatsApp. In this case, you’ll be able to log back into WhatsApp only after seven days of your last use of the app. According to WhatsApp, however, there will be consequences for your messages and account in this case: “After these seven days, your number will be permitted to reverify on WhatsApp without your passcode, but you will lose all pending messages upon reverifying—they will be deleted” WhatsApp’s FAQ page states. “If your number is reverified on WhatsApp after 30 days of last using WhatsApp, and without your passcode, your account will be deleted and a new one will be created upon successfully reverifying.”
