WhatsApp Beta for Android Tests Username Key Feature for First-Time Chats
WhatsApp's latest beta for Android is exploring a new privacy feature that allows users to require a username key before someone can initiate a conversation for the first time. This addition builds on the existing username system, giving users more precise control over who can contact them without revealing phone numbers. While still under development, the feature demonstrates WhatsApp's approach to balancing discoverability and privacy. The new mechanism ensures that messages from unknown contacts are filtered through a voluntary access step.
