WhatsApp has been testing its two-step verification process since November, and is now beginning its rollout in phases. In order to turn on the feature, you’ll need to log into the app, find your way to the Settings page, then go to Account, where you can enable the security measure.
If activated, users will need to enter a six-digit security code in addition to their phone number and text message or voice call verification. They will also be asked to enter their security code once every seven days. Should users forget their security code, they can register an email address with WhatsApp and use it to turn off two-step verification.
WhatsApp said : “We do not verify this email address to confirm its accuracy. We highly recommend you provide an accurate email address so that you’re not locked out of your account if you forget your passcode.”
The messaging service also notes, “If you receive an email to disable two-step verification, but did not request this, do not click on the link. Someone could be attempting to verify your phone number on WhatsApp.”
The roll out of the improved security comes weeks after the revelation of a vulnerability in the implementation of WhatsApp’s encryption protocols.
