WhatsApp to replace phone number sharing with usernames for all users

Meta-owned messaging giant WhatsApp announced on Monday that it will introduce a username system, allowing users to communicate without sharing their phone numbers. This update, affecting hundreds of millions of users, aims to enhance privacy by letting people choose unique usernames to share instead of their phone numbers. The company stated that this move is designed to protect the privacy of phone numbers, especially in scenarios like being added to large group chats or contacting someone for the first time.

WhatsApp emphasized that there will be no directory or suggestion feature, meaning users must know your exact username to contact you. This prevents random discovery and adds an extra layer of privacy. With over three billion users, Meta acknowledged that not everyone will get their first choice of username, but the system will be rolled out gradually to ensure fairness.

The rollout of username reservations will happen globally over the coming months, with users receiving notifications when the feature becomes available in their country. Additionally, creators, small businesses, and organizations will be able to claim WhatsApp usernames that they already use on other Meta products like Facebook or Instagram.

This update adds to WhatsApp's growing list of privacy-focused features, including end-to-end encryption, disappearing messages, and two-factor authentication. By minimizing phone number sharing, the company aims to reduce spam and scam attempts. Experts believe this could significantly improve user security, especially for those who are cautious about sharing personal contact information.

Meta's move is part of broader efforts to address privacy concerns that have plagued the company in recent years. The username system is expected to provide a safer communication environment for both individuals and businesses. However, its success will depend on user adoption and the ability to address potential security vulnerabilities that may arise with the new feature.
