IIE Digital Desk: In an effort to boost privacy, WhatsApp is introducing a new feature for its users' usernames that will allow them to communicate with each other without disclosing their mobile phone number. Despite being seen as an advancement towards user protection, the feature's potential to enable impersonation and fraud online has raised concerns among cybersecurity experts.

Users will soon be able to create their own usernames and use them to start conversations, which will eliminate the need to disclose personal phone numbers to strangers, businesses, or people connected to online communities. In addition to its lack of a public directory or username search, WhatsApp has stated that users will need to know the exact username they are using to start chatting. Users may be misled by fraudsters who generate usernames that closely resemble those of public figures, businesses, banks or customer support teams, making it impossible to trust their accounts. Phishing links, fake investment schemes or financial.

Technology leaders and cybersecurity experts have expressed apprehension that username-based identities may undermine the accountability associated with verified phone numbers. They argue that even small variations in usernames could confuse users who are unfamiliar with spotting fake profiles, making impersonation attempts more convincing.

To address these concerns, WhatsApp has announced several protective measures. High-profile usernames for celebrities, public figures, government organisations, and businesses will be reserved to reduce the risk of impersonation. The platform is also introducing an optional "Username Key," which adds another verification layer before someone can contact a user through their username for the first time.Experts note that the feature itself is not inherently unsafe, but its success will depend on the effectiveness of WhatsApp's anti-spam systems, identity verification mechanisms, and reporting tools. They recommend that users remain cautious when receiving messages from unfamiliar usernames, verify identities before sharing sensitive information or transferring money, and report suspicious accounts immediately.

WhatsApp plans to roll out the username feature gradually over the coming months. If backed by robust security controls and user awareness, the update could offer stronger privacy while maintaining trust on one of the world's most widely used messaging platforms.
