WhatsApp Tests Username Feature Allowing Chats Without Phone Numbers
What Happened — WhatsApp has begun rolling out a beta feature that lets users create a username, enabling conversations without revealing their phone numbers. The change is being tested with a limited group of users and is intended to add a privacy layer to the messaging service.
Why It Matters for TPRM —
- Reduces the amount of personally identifiable information (PII) shared with third‑party contacts, lowering data‑leak risk.
- Alters the data‑flow model for enterprises that embed WhatsApp Business API, requiring updates to privacy assessments and contractual clauses.
- Signals a shift in messaging‑platform privacy expectations that may affect compliance and vendor‑risk evaluations.
Who Is Affected — Consumer messaging users, enterprises that integrate WhatsApp Business API, and any third‑party vendors handling WhatsApp communications.
Recommended Actions — Review your organization’s use of WhatsApp Business API, update data‑handling inventories to reflect the optional username field, and verify that any contractual or compliance clauses address the new privacy model.
Technical Notes — Feature is a client‑side update; no CVEs are involved. It introduces a username identifier stored on WhatsApp’s servers, separate from the phone number. Data types impacted include contact identifiers and metadata. Source: TechRepublic article
