WhatsApp Usernames
On 29 June 2026, WhatsApp announced that users would soon reserve a unique username and use it, instead of their phone number, as the identifier others use to reach them. Days later, India’s Ministry of Electronics and Information Technology ordered the company to pause the rollout, warning the feature “may materially increase the incidence of online fraud, phishing, digital arrest scams and impersonation attacks.” WhatsApp was given three days to respond. As someone advising organisations on both cybersecurity and data protection, I see this as a genuinely difficult trade-off, not a paranoid regulator versus an innovative platform. Both sides have a point, and implementation details will decide who is proven right.
The Good: A Real Privacy Upgrade
From a data protection standpoint, the case for usernames is sound. A phone number is a high-value identifier: it is often linked to national ID and SIM-registration records, it enables SIM-swap attacks, and it exposes users to unsolicited contact the moment it is shared with a stranger, a classmate, or a business. Replacing it with a disposable, revocable handle is a textbook application of data minimisation — sharing only what is necessary for a given interaction. It also brings WhatsApp in line with Signal and Telegram, and gives at-risk users (journalists, activists, domestic abuse survivors, professionals dealing with the public) a genuine tool to control who can find them. Handled well, this reduces the attack surface for harassment, doxxing, and number-harvesting scams that currently thrive on WhatsApp precisely because the phone number doubles as a universal identifier.
The Bad: A New Front Door for Old Scams
The trouble is that a phone number, however imperfect, has functioned as a de facto trust signal in most countries — it typically implies a KYC-verified SIM registration, making it at least theoretically possible to trace a bad actor. Usernames strip that away for first contact….
