WhatsApp to introduce usernames to reduce phone number exposure

WhatsApp is preparing to implement a significant update that allows users to communicate via usernames, potentially making personal phone numbers secondary. This shift aims to reduce the exposure of sensitive personal data for its 2 billion users worldwide. However, experts warn that this change introduces new cybersecurity risks, specifically regarding identity impersonation and scams where criminals use usernames similar to legitimate accounts.

For businesses and professionals, usernames will function as public identifiers, creating a new landscape of digital identity similar to web domains. This may lead to competition for desirable handles. While Meta could leverage existing protection mechanisms from Facebook and Instagram to secure brand identities, specific processes for small businesses remain undefined.

In addition to these structural changes, the platform continues to face challenges with malicious spam and phishing attacks. Users are advised to remain vigilant against messages marked with the ‘forwarded many times’ label, which often indicates mass-distributed fraudulent content designed to steal banking credentials or personal data. To combat these threats, users should utilize the report and block features available on both iOS and Android devices.
