AI Summary

WhatsApp began rolling out username reservations this week, a feature that lets users find and message each other by handle instead of phone number. The change is part of a broader launch planned later this year. Security experts and regulators in India, where the app has more than 500 million users, have raised concerns that the new usernames could enable impersonation. Meta says the shift improves privacy, but critics argue it creates new opportunities for fraud. The rollout marks a significant change in how people identify one another on the platform.
