WhatsApp to let users go by usernames instead of phone numbers, closing privacy blind spot

WhatsApp is rolling out a new feature that allows users to identify each other by usernames instead of phone numbers, addressing a longstanding privacy concern. This change aims to enhance user privacy by decoupling identity from phone numbers, which can be easily exposed. The move is significant as it empowers users to maintain more control over their personal information, potentially reducing unwanted contacts and privacy breaches. This update reflects WhatsApp's ongoing efforts to bolster user security and privacy in an increasingly digital world.
