WhatsApp plans to test a new security feature that will help link user accounts to their email addresses. According to observations in the latest beta version of the app, the option to link the account to an email will be optional and separate from the "two-step verification" feature, which uses email to reset the PIN when forgotten. WhatsApp has not revealed more details about the new feature, nor has it clarified how it differs from the current mechanism for verifying account ownership. However, the new email-based security feature appears to be a promising tool for protecting accounts and conducting verification in specific situations. This feature is still under development and will be available to beta users of the WhatsApp app in the coming period, with plans to release it to other users later on.
