WhatsApp is implementing a new username feature to enhance privacy by allowing communication via unique identifiers instead of personal phone numbers. This shift aims to reduce the direct exposure of personal telephone data. For businesses, usernames may assist in maintaining brand consistency and reducing impersonation risks. Javier Lorente, an MBA professor at EAE Business School, noted that usernames could become a significant business asset, similar to internet domains, and may allow multiple collaborators to manage corporate channels without using personal lines. To combat fraud, WhatsApp is rolling out ‘Scam Alert’ to select beta users on Android. This feature uses on-device machine learning to identify suspicious message patterns from unknown senders. Because Meta stated that ‘no message content leaves the device for classification,’ the tool preserves end-to-end encryption. Security upgrades include transitioning the two-step verification system to an alphanumeric password, expanding passkey support, and introducing passkey-backed encrypted chat backups. New updates expand user control and social features. WhatsApp has introduced a suite of optional parental controls for families with teenagers, typically aged 13 to 17. These tools allow parents to manage settings like profile photo visibility, group access, and interactions with Channels and Status updates via a PIN-protected setup. Parents will also receive notifications regarding significant changes in group activity, such as when a teenager joins or leaves a group, or when a group grows significantly in size. Regarding Meta AI, parents can select between a default setting for users aged 13 and older or a stricter ‘Limited Content’ mode. Meta emphasizes that end-to-end encryption remains intact, meaning neither the platform nor parents can read private chats. Further accessibility updates include a guest calling function. This allows individuals without a WhatsApp account to join video calls via a web browser link.
