• WhatsApp is launching a username feature for enhanced user privacy.
• Users can reserve unique usernames instead of sharing their phone numbers.
• The feature aims to protect users' identities in group chats and first-time messages.
• A "username key" option will add an extra layer of security for new contacts.
• Companies can claim existing usernames from other Meta services.

WhatsApp, a Meta-owned messaging platform, announced a significant upgrade aimed at enhancing user privacy by allowing its more than three billion users to utilize unique usernames instead of phone numbers. The feature is designed to close a longstanding privacy gap, enabling users to communicate without disclosing their personal contact details, especially useful for new acquaintances or in group chats, where phone numbers have traditionally been shared automatically. “We have designed this as a core privacy feature,” said Alice Newton-Rex, WhatsApp’s vice president of product, emphasizing the need for users to know someone's exact username to make contact initially, according to Channel News Asia, India Times, and Al Jazeera.

The feature will roll out gradually, allowing users to reserve usernames that can range from three to 35 characters in length. WhatsApp assures that there will be no public directory or autocomplete suggestions, thus enhancing user control over their contact avenues. This improvement not only minimizes uninvited contact but also aligns with Facebook and Instagram's existing username systems, making it easier for users to maintain identity consistency across platforms, as noted by Channel News Asia and India Times.

In addition, WhatsApp will offer an optional “username key” feature, which provides users with added control over who can reach them. With this key, new contacts would need to know both the username and the key to initiate a conversation, thereby elevating privacy to a new level. The introduction of this feature represents a proactive step towards user-centric privacy enhancements, as Channel News Asia, India Times, and Al Jazeera report.

Moreover, users will be able to reserve usernames as part of WhatsApp's efforts to hold back usernames from high-profile individuals or groups, preventing impersonation. Companies and organizations already on Meta’s other platforms can claim their usernames, offering a seamless transition for brand identity in the messaging space according to India Times and Al Jazeera.
