After years of extensive testing and leaks, Meta-owned WhatsApp has announced the gradual rollout of the highly anticipated "usernames" feature, allowing people to communicate without needing to share their personal phone numbers. This move represents a paradigm shift in the privacy policy of the messaging application used by billions worldwide. The new feature enables users to create unique, memorable digital identities that can be easily shared with friends or businesses. This update is expected to significantly reduce spam and fraudulent messages, providing users with an additional layer of security and aligning WhatsApp more closely with other secure messaging platforms that rely on aliases.
