Overview

• Since April 16, WhatsApp has been rolling out a one-way Info-Chat for official updates, security alerts and feature announcements directly within the app.
• The latest iOS beta introduces unique usernames that replace phone numbers in chats, enabling anonymous communication once widely released.
• Usernames must be 3-30 characters long and use only lowercase letters, numbers, dots and underscores while avoiding domain-style endings or duplicates.
• WhatsApp is developing a PIN protection feature that will require a personal code to verify messages sent to a username and deter unwanted contacts.
• Users retain full control with options to mute, delete or block the Info-Chat channel, complementing these changes with stronger privacy and spam safeguards.
