How to change group privacy settings

WhatsApp has always allowed anyone with your phone number to message you or add you to a group. Just like how anyone can send you an SMS message or email if they have your contact information.
By default, your group privacy settings are set to Everyone. This way, you can easily connect with friends and family, even if they’re not in your contacts list.
For additional privacy, you can control who can add you to a group by adjusting your WhatsApp Settings.
Note: Changes to group privacy settings can’t be made on WhatsApp Web or Desktop. When you change the settings on your phone, they will be synced with WhatsApp Web and Desktop.
