However, with this new feature, anyone can now connect to WhatsApp Web, even in situations where it was previously impossible. It is worth noting that currently, this feature only works with WhatsApp Web and does not allow linking the WhatsApp account to a secondary mobile device using just the phone number.
The feature to link your account to WhatsApp Web by using your phone number is available to some beta testers that install the latest WhatsApp beta for iOS update from the TestFlight app. WhatsApp is also introducing a new privacy feature for community members, which restricts your phone number visibility only to those who have saved you as a contact. The feature is available after installing the most recent update of WhatsApp for iOS and Android.
