WhatsApp rolls out usernames for 3bn users to boost privacy

WHATSAPP is introducing usernames later this year, allowing its 3 billion users to connect without sharing phone numbers. Users can reserve their usernames now to avoid name overlap at launch, enhancing privacy by preventing strangers from accessing personal information. The platform will not have a public directory or suggestion algorithms, requiring users to know exact usernames to contact one another. An optional username key can be used for additional control over who can message a user. The announcement emphasizes the need for privacy in communications, as phone numbers are often linked to sensitive personal information.
